Relay Module Connection

Postby Barbess » Sun Aug 31, 2025 12:27 pm

Hi everyone, I'm a beginner in electronics and I would like your advice. I have several sensors and a ESP32 board powered by the same power supply. I would like to use a relay module to turn these sensors on and off, and I would like to know if my setup is correct or not.

Thanks for the advice and recommendations.

please share the connection chart. Mention which pin of the ESP32 is connected to which pin of the relay module.
