Voltage Sensors with Raspberry Pi

Thu Jul 11, 2019 2:55 pm

Hi all! I wanted to add 2 V sensors and 1 mV sensor to my raspberry Pi. I have a plate that adds 8 ADC pins (DAQC2 pi-plate) so that part is covered. However, I was wondering what people thought was the best option for me to pursue this. I am trying to get values from a generator. Can I just simply connect it to a 25V Voltage Detector Module 3-Terminal Sensor. I am a bit shaky on core electronics concepts, so what do I do if my voltage is incredibly high? Do I have to keep each input that eventually goes to the Pi under 3.3 V?

If you connect 25v to your pi you will instantly distroy it.

From the questions you have asked on this forum I would suggest this project is way above your skill level especially if we are talking about a mains 240 /415 v generator.

You not only need to increase you pi use skill kevel but also you need some professional electrical training.

Mains AC can and will kill you and burn down your house given the chance.

What is a "25V Voltage Detector Module 3-Terminal Sensor"?

And what sort of "generator"?
