2 Channel Wi-Fi Relay Module Using ESP8266 Node MCU

The project described here is an ESP8266 Node MCU Two Channel Relay Module. This board enables users to control 2 x relays remotely. The 2 channels can be controlled remotely using a webserver/WiFi connection. The project works with 5VDC. Two LEDs indicate relay operation. Screw terminals help user to connect devices and power the supply. Relay output has 3 contacts normally closed, normally open, and common. Relay can drive a load up to 10A/250VAC or 10A/30VDC. It can be used in applications such as IoT and smart Home/Home automation.

The board can be connected to a server through a TCP Client and also can be controlled by HTTP. With this module, users can upload firmware and can create a versatile IoT project. It is suitable for your smart home and IoT project with network control.
