I have a use case to tack a Ruuvi onto a liquid level measurement sensor which reports level a as a voltage between 0…supply voltage level
the sensor must be powered on for 200mS for a stable signal and thereafter can be powered down; I think I can get the powerup/powerdown cycling baked by analogy
storing calibration values for full/empty would be helpful
I’d be grateful for an example/hint to to measure voltage with a Ruuvi -
best regards
Michael
edit: I guess I’ll study the battery measurement code for a start
