Hi, the text at 4:00 is too small, and thanks for the great content

I like your videos, Andreas. They have a good "signal/noise ratio"

These sensor / board comparison videos are my favorite. They're always informative and help me out in my projects.

Congrats: You hit the 200.000!! And again a great Video. Thanks for that and stay healthy. Have great easter holidays.

Congrats Andreas!! Your videos should be within a Public Electronic Wikipedia as a reference! Greetings from Spain!

Thanks again for a great video. I specially enjoy these compilation videos which compare similar devices and helps us followers save a lot of time searching for the info you kindly bring us in the usual well structured and easy to follow videos

Thanks, Andreas! That will help me for an advanced line following modul. See you next UKW conference hopefully!

Worked so hard trying to fix the APDS9960 with no luck, thank you!!!

I want to thank you for your work. You've been so helpful, every time I want to buy a new sensor for a project there's a video of you trying the most common available and making a thoroughly made review about it. So, thank you you've made much lighter the work otherwise I've had to make in order to choose the right sensor for my project

You have covered all sensors in my treasure. Nice explanation. Thanks !!! ✨✨✌

Thanks for the informative video. I made a rgb sensing setup yesterday using the AS7262 chip. Though expensive, it is easy to work with and accurate.

I love the way Andreas shares his own mistakes and that self-deprecating humour is wonderful!

This video arrived in the perfect time for me, today I was researching the detection of gamma and beta radiation using photodiodes as a replacement for Geiger-Müller tubes, so this video was very handy! Congrats for the 200k! :D

Thanks for dedicating your time to another great video! :) Right now we are developing a project that needs a light sensor and after a close examination we've went fo the same IC TCS34725.

Thank you for your effort and time spent on this Topic. Regarding your awning: What also could be helpful for you is the cloudage. I am measuring far IR Temp with a Melexis MLX90614 and environmental Temp with an BM280 or SHT35 (you would prefere the Swiss one). Then I calculate (or rather more guess) the cloudage.

Well that video brightened a dull day (sorry). Learnt a lot - never realised the sensors where so different. I’ll be following up the gesture sensor, thank you for publishing your code for that. One thing to note - a significant amount of ‘white’ paper is actually blue to give a clean cold look rather than a warm tint.

Thanks for the video. I've been using the GY-49 / MAX44009 module for measuring lux in my greenhouse (to calculate the total moles of light the plants receive). It claims to have a range up to 188,000 lux.

hi Andreas i like those videos when you talk about different sensors and compare them keep up the good work , i think your channel will become the reference in sensors boards for arduino and MCUs

You know the wife is paying attention when she starts mocking your engineering choices. :D Thanks for the comparison -- I hadn't even heard of half of these. Time for another shopping round...

An LED will also work as an ambient light detection sensor. First used IIRC by HP in calculators, measuring the voltage of 7-segment displays where the LED segment was off, to determine the current to drive the display segments, according to ambient light. So you wouldn't suffer retinal damage in the lab from a display readable in outdoor daylight.

I really like the last sensor

In my current project I am designing a sensor for determining distance with a red 5mW laser diode. I would like to be able to use these readings to control the response of a small dc stepper motor for controlling an X/Y axis small milling table. I have a lot to learn and I am sure this information will set me in the right direction. I started thinking about this project only earlier today, so this video came out with perfect timing for my needs. Thank You for all of your help over the past few years that I have been developing my understanding of these concepts.

Nice video. Btw, don't worry, my wife also laughs with my experiments quite often.... so you're not alone ;-)

Sure, Maaaaan. I like your form to explaint the sensors that I use, thank you very much

I worked in lighting for 10 years. The best light sensor in lux, in my humble opinion, is the Texas Instrument OPT3001. I scanned across the entire visible spectrum, from 380nm to 780nm in 20nm steps, and the sensor actually fits almost perfectly the CIE-defined eye sensitivity curve. It is the best light sensor I could measure. In addition to adjusting to the sensitivity of the human eye, it can measure from 0.1 lux to 100,000 lux. This dynamic range of measurement is amazing.

Hello Andreas, I have worked for TAOs since long before we were purchased by AMS. You are correct the TCS3200 is outdated. Also the TCS3414 as well. Neither of these have IR filters because when they were designed the technology to deposit the filter directly on the chip was new and very expensive. You are right the TCS34725 is the only AMS part you had that is not obsolete. BTW the Avago part is really an AMS part. TCS3223 I believe. AMS now has a TIme of Flight device you should try. This is very interesting part. Oh, and that TSL2561 was used as the Ambient Light Sensor by Apple in the very first iPhone. Those have a very wide dynamic range because you have an analog gain setting and you can also set the integration time from 2.7ms all the way up to 65535 x 2.7ms. Great video! DE N5BOC

Hi Andreas, video with lot of tehnical details and extensive comparison of different sensor available on the market. I feel bad that I did not find your video for this long time.. Once again Thank you so much.. I see a German accent in your explanation. Danke schön.

Very interesting video, many of these devices I have never used. Things have certainly come a long way since the OCP71 (or OC71 with the paint scratched off!). I have a WEMOS which monitors the temperature and humidity in my loft, I think I will add a light sensor to warn if the loft lights are left on when the hatch is closed. Bob

Happy Easter, Andreas! Thanks for another great video!

superb explanation of content and inclusion of initial targets and end results for complete understanding! God bless you this video came as ray of hope for my works!!

Very glad to have found this channel and this video. Would like to have seen more info on UV sensors, particularly for a weather station to detect the UV level outdoors.

Hello, I use the MAX44009 lux sensor from Maxim integrated, widely available from Aliexpress. I use it to adapt the brightness of my displays

a useful and educational video. liked it very much. The information you provided useful very well for me.

Always interesting ideas to get inspiration in the Arduino community thanks for sharing.

wow , I thought I had alot of light sensor modules to test, wow Some of these I have never seen.

This video is right up my alley

Thanks for a lovely video on light sensors! Really appreciate your work and dedication.

As always very informative and useful. Thank you Andreas :)

Thanks in advance for your comments

Great Work Andreas!

Very comprehensive as usual and a superb reference for the future.

Bloody hell, what a great video :-) Thanks a 1 000 000 for the content, very interesting and illuminating informations.

Frohe Ostern, Andreas und vielen Dank für die tollen Videos. Ich freue mich, dass du die 200.000 Abonnenten erreicht hast - ein großartiger Meilenstein: Gratulation! Bleib gesund in dieser schwierigen Zeit! Vielleicht brauchen wir jetzt eine Definition von dBs(ubscriber), dann wünsche ich alsbald +3dBs ;)

Thank you for another interesting video in a series that will hopefully be continued 👍 At last no sensor or web based service can replace the wifes skills and predictions 😁

Thanks for a great video! I use VEML7700 or VEML6030 mostly for it's low sleep current. Not at Aliexpress but at Adafruit as a module.

It is helpful for my quantum photonics research.

Great test as always Thanks for sharing 👍😁

Very usefull these overviews of sensors.

Thanks for such a nice sensors comparison video.

Greetings Andreas, I am working on a personal research project but because of quarantine I can not buy any precision light measuring sensors and had to use the LDR that I already had at hand, but due to LDR's extreme variance with the change in temperature, it is far from precise, stuck at home and cannot buy anything, so I had to come up with an alternative, so I am using LEDs as a light sensor, I have tested many LEDs and came to a conclusion that the LEDs which light up at least voltage give the best results. I kindly propose the idea for one of your future videos to analyze and show how feasible it is to use an LED as a light sensor. Regards, Tanishq

Hi Andreas, thanks for another great video. I just want to mention that LEDs can also be used as light sensor for some applications. I am using an array of 3 LEDs for an ultra low cost 3-channel spectrometer.

Very comprehensive review.. .quite helpful to have for future reference

Yes there is another one which I prefer: The TEMT6000. I also use it to measure sunlight and control my sun roof

Welcome to the game of sensors...

@andreas If you use a lux sensor for your awning you'll need to keep adjusting it every winter for when you want to sit out in the sun. It might be better to use a temperature sensor instead. Or maybe mix both (lux and temperature) and make some Node-RED flow for it! Sounds like a project! 😉

Great video! Thank you

great work Andres

Well done. (again) Thanks.

Danke für das wieder sehr informative Video, Andreas es sind die Sätze wie, meine Frau machte Witze über meine Fähigkeiten die mich jedes mal schmunzeln lassen und ich sozusagen eine tiefe Verbundenheit verspüre, mir geht es ja genauso. Oder so Sätze wie in deinem LoRaWAN Video als es darum ging die Pins vom Draginoboard einzutragen "Otherwise you scratch your head an nothing goes" (Video 117) soooooo genial :-) Hey schöne Ostern und bleibt gesund!

I recently use VEML6030/VEML7700 ALS sensor with perfect human eye response. Also have a look about VEML6040 RGB sensor. All from Vishay. Nice packaging, but a little bad interface

Have you considered putting sensors in solar garden lights? You get a solar panel, a battery and an enclosure for a relatively cheap price. For instance temperature and moisture measurements in the greenhouse. You probably need a buck-converter to get the 3.3v needed from a 1.2NiCd or 3.2LiOn, but still. If the ESP went into deep sleep, and only sends occasionally, I guess most lamps could supply the power.

Could you 'clear' up what is meant by 'clear' on the light sensor? I would think they mean 'white', but that's just a software combination of R, B, and G, so I'm unsure if they might mean something else.

You can get filters for most wavelengths which is handy in some projects to filter out other types of light you are not interested in measuring and which can interfere with your results.

At 10:19 you're talking about the TSL2591 as not recommended, but the red box on the left doesn't include that sensor. Looking at the AMS website, it actually says "Industry leading dynamic range which drives both ultra low light sensitivity and bright sunlight operation" about that sensor.

really great and extraordinary content ... but have just a view sensors you already mentioned.

Happy Easter, Andreas! Great video! I wonder wether one of the proximity sensors would be accurate enough to use in a 3D printer for auto bed leveling?

If someone really wants to measure the human perceived color values, better use a tri-stimulus sensor in the XYZ colorspace. They are also made by AMS, an Austrian company. There is also an option for sensing 18 channels in parallel with 20nm bandwith for each channel.

ive got an "APDS-9960" but i cannot get it to work... from what ive read its actually only a APDS-9930.. which doesnt have the RGB functionality (what i purchaced it for!)..seems there a few fakes getting about...Thanks Andreas, i know what to look for what purchasing light devices now!

Grüezi from Zurich! I have a project currently based heavily on home sensors for monitoring house plants. Light is obviously an important variable to monitor so have been prototyping with lots of different breakout boards. Currently developing the design on a PCB and I've found that a lot of the lux sensors are hard to source when building yourself. Currently, I'm working with the BH1715 (poor results), VEML6030 (excellent I2C), and the TEMT6000 (analog, quite primitive). Would love to experiment with the UV as this is also an important aspect of plant health so will try to integrate a few extra sensors into the next version!

Clear 10mm LED, two digital pins = very good detection of sunlight levels. In a nutshell, the LED is capacitively charged by feeding a reverse voltage into it (pins set to OUTPUT), then the decay of that voltage is measured as it slowly leaks into the (now) INPUT pins of the MCU. The more light there is, the faster it discharges. I've used it successfully for quite a few projects, no ADC needed.

Good video Andreas. Greetings from Ensenada Mexico

Hope this amount will buy you are beer during your vacation! Enjoy your summer :)

Andreas thank you for your vídeo. Excelent. I used APDS 9960 for a project wich needs to get light colour temperature (Kelvin) it is an excelent sensor.

For proximity and lux sensors there also is the SI114X series. I'm waiting for an SI1145 which can even approximate the UV Index by combining the IR and Visible Light sensors. Frohe Ostern

Frohe Ostern Andreas!

Great vid Andreas! I would really love instructional on how to make a colorimeter with ESP32.

Hi Andreas, nice video like always. I have a question for you :) On the ESP32, if someone creates a wifi Network with the same SSID and the ESP32 tries to connect to it, the password that it sends to the router is Encripted? Or the fake Router can know your password in plain text with this kind of attack? Thank you for your amazing videos. Thx from Spain ;)

Great video, thank you :)

There has to be this intuitive bond. I am currently working on a project in which I measure the UV-A and UV-B radiation, and if the brightness is exceeded, the shutters on the windows are to be automatically shut down until the UV-A and UV-B levels are again a comfortable level in the room reached. 🤗😘 In my Project I desire to use GY-6075 Light Sensor Modul and BMP280 for Weather Control with a Node MCU ESP32 Dev Board and a 433 MHz RF Transmitter to control the Somfy Window automation.

Thank you very much for this video! I found it very useful :)

Your awning is to stop it getting too hot. Think infra red. A heat sink with a temp sensor might be easier and more effective! Depends if you want an engineers or a geeks solution!! Your sensor comparisons are really useful. Stay well.

The TCS3200 may have use in non digital applications. Life is about change, and, that everything repeats itself. I know, that's odd, but if the digital age ended, (EMP?) you could essentially hook one up to an antiquated panel meter via transistor and smoothing filters.

I really like and appreciate your videos. I am currently using TSL2561 sensor witch includes visibible + near infrared diode and another wide range infrared diode, which is very interresting because it lets me calculate the Lux by subtracting IR reading from Visible+IR. This help me measuring light illuminance in Lux with high precision by eliminating IR interference. This sensor also gives me the possibility to measure light power with good precision by using light+near infrared diode and wide range infrared diode and using a factor calculated for most common sun light spectre profil. The problem I have with this sensor is that the range is quite low and didn't exceed 40000 Lux which is not enough for day sun light especially here in Morocco. I didn't find this information in your video when you talked about TSL2561. Could you please give me your opinion about this issue and if there is a good alternative to this sensor for my application: Weather and fertilisation station for Agricuture. For more details here bellow a link to my collected data. Thanks a lot for your high level and extraordinary video content: www.abrobotics.be/siliconceptsarl/METEO/meteoframe.php

congrats on 200k

Thanks! This video useful for me.I wonder how to create a strobe lux meter

Hello sir, thank you very much for this video, I need advice from you, I need to build a sonometer with decibel and i need a sensor that can give me analog values of sound, can you recommend me a sensors ?? thanks

which would be best sensitivity to detect light in bedroom when sleeping from curtain leakage?

Ich habe seit mehr als 800 Tagen einen Lichtsensor im Einsatz, der minütlich die Helligkeit misst. Damit kann man eine Steuerung für die Markise bauen. Zu bedenken ist das im Winter die Helligkeit bei voller Sonneneinstrahlung genau so hoch ist wie im Sommer bei starkem Regen. Die Schaltschwelle müsste dazu also dynamisch sein. Bei Bedarf kann ich dir meine 2,5 Jahre Messdaten gerne zukommen lassen.

Awesome video keep it up .

Next on MOTION SENSORS... which can be used in day to day life.

Thanks !

Hi Andreas could you please do a tutorial of a NBE-IOT hardware combined with a simple sensor????

I followed your advice on 11:14 . First I subscribed, then I unsubscribed again at 11:17. Good advice!

Hi Andreas, great content as usual and very helpful for a project I have always wanted to try: I would like to read the outside color temperature using one of my arduinos, then integrate it via mqtt into my node-red to adapt the Philips Hue Lights in a room with a tiny window to the same color temperature (doing this manually gives a much better perceived light atmosphere, but with changing lights outside (cloudy->sunny->cloudy) this is also irritating). Maybe some expert here has an idea: would it be sufficient to convert RGB values to Kelvin for that matter or would I need other values to analyze light intensity? Congratulatitons on 200k! :)

The uni-t lux sensor has a white plastic lens, I wonder if it does affect readings in any significant way? Since if we were "to deploy" a device with a light sensor it should be covered with something to protect it imho. Btw. I'm running like 2 years now a LDR to do stuff on sunset/sunrise and after fine tuning of sensitivity levels in software it works fine. The program also checks the time so the trigger runs only these 2 times a day.

I found your video interesting. Could you advise me on this... At my job, we cut steel shavings that we stack on top of each other. I would like to build a device that, using a CCD sensor or camera, can vertically scan the stack of pieces and count how many are in the stack. What sensor would you recommend? Thank you.

EXCELLENT POST!!!🙏👌

The Veml6070 was missing, it’s a great UV sensor

2:19 - It doesn't have to be specifically R, G and B. You could also measure at Cyan, Magenta and Yellow. Or any other mutually complementary hues. Basically, any three hues that are at 120º from each other on a colour wheel can be used to determine the dominant wavelength. But, as you know, reading just the wavelength won't allow you to distinguish (for example) red from salmon pink, or yellow from brown, since those differ in brightness and saturation as well. You can calculate those in software if the sensor outputs the three channels (not just its own internal calculation of the wavelength) but, as you mention later in the video, many of those sensors have very irregular overlap between the channels.
