The Single Channel Relay Module is a versatile and efficient solution for controlling high-voltage devices, such as lights, motors, and home appliances, using low-voltage microcontrollers like Arduino, Raspberry Pi, or other embedded systems. This module is equipped with a relay that acts as an electrical switch, allowing you to control circuits with a higher voltage (up to 250V AC or 30V DC) through a low-voltage microcontroller or GPIO pin.

Featuring a built-in optocoupler for electrical isolation, the module protects your microcontroller from voltage spikes or surges from high-voltage circuits. The relay is easy to control via a digital signal from your microcontroller and typically includes a transistor and diode for further protection. With a 5V operating voltage, the Single Channel Relay Module is perfect for creating automation projects, home automation systems, or IoT applications where you need to control external electrical devices with ease.
