The HKD ESP8266 1-Channel 5V 10A WiFi Relay Module is a smart wireless switch solution for home automation, IoT projects, and remote device control. Built around the ESP8266 ESP-01 WiFi module and a microcontroller, it allows you to control electrical devices via a smartphone app over a local area network (LAN).
Supporting multiple operating modes (STA, AP, STA+AP), this relay module can either connect to an existing WiFi network or act as its own hotspot. With a maximum transmission distance of up to 400m, it provides reliable performance in both residential and industrial settings.
It supports serial port communication for configuration and control, with diode protection and fast response times for added reliability. Once configured, you can easily switch devices on or off wirelessly, making it perfect for smart homes, automation systems, and remote switching applications.
