![]() 5V/1A power adapter and APP ESP TouchDemo.Once it is programmed and powered it will look after itself, making it ideal for use in internet of things IOT based projects. This will require configuration via UART prior to full operation. The relay is controlled via the included ESP8266. When a signal is received an audible click can be heard as the relay triggers, connecting the output pins. A red power activation LED that lights when a signal is received on the IN pin. The module has an LED that lights relative to the state of the module. This allows you to build in device control, operating remote lights, or triggering systems when the module is supplied with a signal from an ESP8266 module. This is a 1 channel relay module that can be used to activate up to 250V AC and 30V DC. This module is ideally suited to controlling larger voltages in your project through WIFI. It will send the serial port instructions to the cell phone APP and Implementation within the local area network (LAN) for wireless control relay. This WiFi relay module carries an ESP8266 WiFi module and microcontroller.
