Gravity: Easy Relay Module

The traditional relay module has complicated wiring and is not friendly to beginners or students. This simple switch module simplifies the wiring method for connecting traditional relays. The input end is equipped with an adapter, which are compatible with many power sources, battery boxes, DC power supplies, power banks and more.

While simplifying the wiring mode, the functions of relays NC and NO are retained, and the normally open and normally closed modes can be switched by simply adjusting the toggle switch.

DFRobot’s latest easy relay module uses a standard Gravity sensor interface and supports a wide voltage input of 3.3V-5.5V, making it easy to connect with a range of development boards including the Arduino. Meet your needs in control applications such as robot control, light control, smart home, security and more!
