This WiFi relay module carries an ESP8266 WiFi module and microcontroller. 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 module is ideally suited to controlling larger voltages in your project through WIFI. This is a 2 channel relay module that can be used to activate up to 250V AC and 30V DC. 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. The module has an LED that lights relative to the state of the module. A red power activation LED that lights when a signal is received on the IN pin. When a signal is received an audible click can be heard as the relay triggers, connecting the output pins. The relay is controlled via the included ESP8266. This will require configuration via UART prior to full operation. Once it is programmed and powered it will look after itself, making it ideal for use in internet of things IOT based projects.
