RELAY
描述
RELAY, 是一款继电器 Unit.能够控制DC/3A-30V或AC/3A-220V级别线路的通断.它实际上是用小电流去控制大电流运作的一种自动开关.故在电路中起着自动调节、安全保护、转换电路等作用.Unit提供3个引脚: ON、OFF、COM.通过编程GPIO输出高、低电平控制,公共端COM与ON、OFF其中之一连接.

Atom Lite control device with Alexa. In my house, Amazon echo is located in every room, and the lighting of living room is controlled by Alex
Using the M5StickC, we developed a product that allows you to wash your hands without touching the device.
The mechanism is simple to monitor the value of the water temperature sensor with the M5Stack, and heater power is controlled by the relay
