Enviro pHAT - AC or DC Input?


#1

Hi there,

I’ve got question concerning the Enviro pHAT and the ADS1015 inputs.

After purchased a [Non-Invasive Current Sensor - 30A] and its my understanding that the low voltage output is AC. In order to connect it to the Enviro pHAT must it converted DC first?

Anyone got any advice?

You’re correct. It should be converted to DC.

I believe you may need a circuit like this: https://en.wikipedia.org/wiki/Precision_rectifier
