ESP8266 WiFi 5V 1 Channel Relay Module

220.00 EGP

The ESP8266 WiFi 5V 1-Channel Relay Module combines an ESP-01S WiFi module with a 5V relay, enabling wireless control of high-voltage devices (up to 250V AC/30V DC) via WiFi (TCP/IP). Perfect for smart home automation, IoT projects, and remote switching, this compact module allows you to control lights, appliances, motors, and more from anywhere using a smartphone, web browser, or voice assistant (Alexa/Google Home).

With easy Arduino/NodeMCU programming and low-power operation, this module is ideal for DIY enthusiasts and developers looking to add WiFi-controlled switching to their projects.
