The IR Relay Shield utilizes four high quality relays and provides NO/NC interfaces that control the load of high current. Which means it could be a nice solution for controlling devices that couldn’t be directly controlled by Arduino’s Digital I/Os. The onboard infrared receiver allows you to make infrared remote control fan or other smart home project. It can be plugged onto the Arduino UNO R3 / Arduino Mega2560 or the other compatible board and it can avoid the trouble of connecting cable. With an infrared remote controller(with a CR2025 lithium battery).

Feature:

Can be controlled by infrared remote(38KHz);

Standardized shape design for arduino shield;

Driven by 5V / 3.3V normally closed contacts open, normally closed contact closed;

Working status indicators for each relay;

4 x M3 screw mounting holes, easy to install;

Note: Remove The plastic sheet before you use the infrared remote controller
