Poor air quality can lead to many negative health effects as well as can cause tiredness, headaches, loss of concentration, increased heart rate and so on. Monitoring the quality of the air may actually be more important than you realize. So, in this tutorial we will learn how to build our own Air Quality Monitor which is capable of measuring PM2.5, CO2, VOC, Ozone, as well as temperature and humidity.

You really should need to form a KIT COMPANY for STEM. Many kids and adults would benefit from a subscription where each of your wonderful kits would teach them much more than they could learn in schools. Your amazing skills should not go to waste. I'm surprised how much effort you put into these projects, you are great engineer, teacher, and person to provide these great ideas and videos. The biggest problem for individuals is sourcing small quantities and the waiting from each vendor on parts. A kit would allow people to quickly move forward to learn and enjoy. The only item would be the 3D printer, which many people who are interested in STEM already have.

You can get a Sciosense APC1 evaluation kit for that, just plug it into your laptop and use the software they provide for that. The evaluation kit is different than the sensor by itself, the evaluation kit (EK) comes with the usb cable and software and it works perfectly for 1 sensor.

My greatest compliments for your design. I build it and it works perfectly. Very good thinking about features and timeline. I made some adjustments so I can easely exchange sensors, but for now I cannot imaging what I should change. Calibration is for me less important compared to more or less value readings. Maybe the loss of data when disconnecting the power could be a minor issue to solve. Thanks for all your time! Great job!

Don't get me wrong, the thing is very well made, and I understand that not everyone is comfortable around ESP8266, but this project seems to be a perfect fit for one of those. - No need for RTC (just get time from internet (at power up) ) - Upload new sketch over the air. - Check your graphs and data on any android phone (can even skip the display.. which is expensive)

Excellent project for the right person. I built one 3 years ago. No LCD, since I used a ESP8266 module instead of a promini, and did everything through the browser. I only installed DHT-11, MQ-5, MQ-3, MQ-9 and MQ135, VEML6075 UV sensor, and DSM501A PM2.5 dist sensor, which was $4! I think my project cost about $25-$30 Yours is in excess of $100 without a PCB.

Awesome explanation as always. Out of curiosity, did you consider using BME680 sensor from Bosch during the design phase? Because it does the work of PM503 and DHT22 combined, plus it even has some kind of pressure sensing, which affects whether pollution levels build up.

@negotiummeum9643 2 жыл бұрын
@@hugodc1225 Oh so PM1 and PM10 are included? That's great! I missed that one, sorry:) Well HCHO (hcoc was a typo) (although the real formula always used to be CH2O ... dk why manufacturers have changed it to HCHO) is Formaldehyde - one of biggest indoors pollutants nowadays to worry about. And CO (unlike CO2) is Carbon Monoxide - an infamous "silent killer"! The stuff is lethal. There could be a fire in neighbor's flat and CO can kill you even before your smoke detector/alarm triggered. Although of course it is worth to have CO detector alone (next to Smoke detector) in few places of your home.

@astrostevehobby5096 3 жыл бұрын
@@XuanGOD All the boards are labeled a bit different. But as long as the sensors don't take too much current, you can power them from the 5v pin. You might want to Google "Feeding power to Arduino: the ultimate guide" and read about how to feed the boards power (even batteries). For my larger projects where the parts I hook to it take more power than the Arduino can supply, I use a regulated 5v power supply, and input power to the 5v pin (not recommended, if you read the article I mentioned), and I can power the sensors not from the Arduino itself, but from the power supply, which can provide more power. In that case, just don't let the power run thru the Arduino first, the traces can only have so much power running thru them. I'd assume most projects and sensors would not be a problem. You'd have to Google how much power your particular board can supply. For the ESP8266 type boards - I have not used one of those yet, and an unfamiliar with them, except that it can be supplied with power from a USB charger.
