Part 6 - Bathroom Mirror with mirror heating

I have a large bathroom mirror with 2 (engraved) touch sensor ereas, surround LED lights (CCT) and a mirror defogger (220v controlled by a relay).

Materials

ESP32 NodeMCU board

Relay module 1 channel – contacts 10A/250VAC – coil 5V

 

 

a mirror defogger (220v controlled by a relay) installation

将NodeMcu的D0 <---> 继电器的IN
NodeMcu的VU <---> 继电器VCC (由于继电器需要5V电压, 此端口提供5V电压)
NodeMcu的GND <---> 继电器GND

强电部分连线 	
火线220V----> 继电器公共端(COM) ----> 常开端(NC) --> 电灯 (除雾膜)<---零线
