The 5V 1 Channel Relay Moduleallows low-voltage controllers to safely control high-voltage or high-current devices. It is widely used with boards like Arduino Uno R3, Arduino Nano, and ESP32 Development Boardto switch appliances such as lights, fans, and motors.
The 5V Single Channel Relay Module is an electromechanical switch that enables microcontrollers to control high-power devices safely. The module includes a relay, transistor driver, and optocoupler protectionfor reliable operation.
When the control signal from a microcontroller activates the relay, the internal switch changes state and allows the connected device to turn ON or OFF. Because of the relay’s electrical isolation, the microcontroller remains protected from high voltage circuits.
This module is commonly used in home automation systems, IoT projects, industrial control systems, and smart appliance control applications.
