RCWL-0516 Microwave Radar Sensor Module – Human Body Induction Switch For Arduino

Hey DIY folks and makers!

If you’re working on a project that needs to detect motion, this little module is awesome.

It’s the RCWL-0516, a microwave radar sensor that works as a human body induction switch.

Unlike standard PIR sensors that need a direct line of sight, this one uses Doppler radar, so it can sense movement through plastic, wood, and even some walls.

Super sensitive and perfect for lighting projects, security systems, or any kind of presence detection.

It’s a single module, unbranded generic, but it’s the popular RCWL-0516 chip that everyone uses in their Arduino and ESP projects.
