📌 Overview of 1 Channel Relay Module

The 1 Channel Relay Module is a compact switching device that allows low-power microcontrollers to safely control high-voltage appliances. Designed for IoT, Arduino, and DIY projects, it provides electrical isolation between control circuits and output loads, ensuring safety and stability. Moreover, it supports both AC and DC loads, making it ideal for home automation and industrial projects.

The module works seamlessly with Arduino, NodeMCU, ESP8266, and Raspberry Pi through a simple digital input pin. As a result, it is one of the most popular relay modules for beginners and professionals building smart systems. In addition, the onboard LED indicator provides a clear visual status of the relay’s operation.
