Review on πŸ” DEVMO 2PCS Microwave Doppler Radar Motion Detector Sensor RCWL-0516 - Improved Compatibility with Ar-duino, Raspberry PI, and Increased Efficiency as Human, Rat, and Cat Detector by Josh Chenier

Revainrating 5 out of 5

Use a satellite dish to find out when something is moving in a large area.

Incredible sensitivity when used with reflector, horn or horn and purchased satellite dish. Control an opto-isolated triac to turn on the light. SWEET.

Pros
  • Motion Detector
Cons
  • Big and chunky
