Relay Module
The Relay Module acts as an electrical switch controlled by microcontrollers like Arduino or Raspberry Pi. It allows low-power devices to safely control high-voltage loads such as lights, fans, and appliances.
How It Works?
The relay contains an electromagnet that, when energized, closes or opens the circuit connected to the load. When the Arduino sends a HIGH or LOW signal, the relay switches accordingly, enabling automation and remote control.
Key Features
- Controls AC or DC devices using Arduino
- Optocoupler isolation for protection
- Available in 1, 2, 4, and 8-channel versions
- Indicator LED for relay ON/OFF status
Applications in Robotics & IoT
