#40979 Hello Guys,

I want to meassure the energy consumption of my house. For this I want to measure the rpm of a ferraris energy meassurement with a cny70 sensor.

How I have connect the Sensor with the ESP? I couldn´t found anything about that with an esp8266 or 3.3V.

I want to program this with Arduino.

Thanks for your great support.

Tobias
