Power Sensing via Power Module to Rasberry PI

(Andrew) #1


I will be powering a Rasberry PI via a UBEC hanging off the Power Module.

How do you measure battery voltage etc via the Rasberry PI. The available outputs on the Power Module are “V” and “I”.

Any help appreciated.

The voltage/current output of those modules is an analog output. This requires an analog-to-digital converter (ADC) to read the value. The raspberry pi does not have any ADC built in. You will need some external adc hardware, or a microcontroller like an arduino.

Awesome Jacob - thanks for the pointer, I will check it out…
