I haven’t seen this sensor yet, what exactly does it do? Simply a 0/1 output, or analog like a volt meter? Do you have a link to it?


#3

It’s a voltage divider.
Connect minus to Arduino Gnd and “S” to Analog pin.

Or simply make voltage divider and use @tad.dvor code :slight_smile:

Cool, even simpler yet.
