Hi Robojax, perfect video! If i buy a 30 ampere version, do u think i can handle 20 ampere for hours without melting the board? This board behaves like a resistance, do u know how many ohms? Moreover, if sometimes i have for a instant 50 ampere because of the start of a pump, do I melt the board? What I read as measurement when i have 50 ampere?
@robojax 3 жыл бұрын
Hi and thanks. I would suggest using Winson sensors introduced in this video kzfaq.info/get/bejne/sJOja7inqL2rqI0.html and the Allegro is based on Hall Effect and there is no resistance on the path. I believe I have explained it at the very beginning. There is about 30 millisecond or 100 millisecond delay but the reading is whatever you have. 50A is 50A. this module may handle excess of current for less than a second but if you are going to measure 50A, then use different modules.

see here page 2 of datasheet: www.sparkfun.com/datasheets/BreakoutBoards/0712.pdf the 5A verison will generate 180 mV/A so 185mV for every 1A. Analog input of Arduino UNO can read from 1mV to 5000mV (or 5V). So yes for 1mA (or 0.001A) so to get 1mV (the minimum) 1÷185=0.0054A or 5.4mA and this is the minimum. you can do the calculation for 30A and 50A version by looking at the datasheet.

2:36 I guess the actual current (of up to 30A) doesn't actually pass thru the chip's pins (it takes a huge wire to handle 30A!). ACS712 works thru indirect sensing. As can be seen in 2:44 the actual current Ip merely passes nearby and the chip has terminals to sense the magnetic field strength and output into proportionate voltage accordingly.
@robojax 3 жыл бұрын
The actual current must pass through PCB and through the chip to get measurement. I've shown the datasheet and pins.

Your projects needs some work. You need to disconnect the switch from the door of your car and make them all pass through the switches they have to they are always ON and you will need 4 channel relay like this kzfaq.info/get/bejne/jcidZrB0ss2xj6c.html or something else to control them. You can program this module so all 4 day can be turned ON or OFF. I do not have time to do this but you can start from this. 1-First make sure this module can work and instead of turning the window, connect 12V or 5V bulbs. Making sure they work the way you wan them to work. 2-then change the switches on your car so they are always ON 3-connect this relay with your push button to the car

Hi sir, but your code was not working on mine (30A sensor + i didn't change the code at all) The current output was V: 1.549V, I: 23.47A while there was no load connected to the sensor.
@robojax 6 жыл бұрын
for ACS712ELCTR-30A-T, then 66mV per Ampere. and your value 23.47 x 0.066= 1.549V is correct. then your wiring should be checked. Disconnect the current sensor from arduino what do you read? is your voltage 5V. Check the voltage.
