Revo voltage sensor DIY
« on: February 29, 2016, 04:53:48 pm »
Did my own voltage sensor for 3S battery today. (10K/3.2K divider)
Cannot get any intelligent voltage reading even after calibrating the sensor. Notice that I do not have current sensor.

I can calibrate the voltage but I cannot see any value changes related to voltage going down.
Any Ideas ?
What is the difference with adc0 and adc1 ? I can get voltage sensor out from both.

Adc1 (pin4) and Adc0 (pin3) refers to the two pins used in PWR port.

Look this page:

actually I was already on that page. ADC1 is the right one for the voltage.(figured after testing)
My problem was that my ground wire was loose.
re-did the soldering for my homemade sensor and now I am getting better readings.

Sometimes works better with ground wire ;)
