The RCWL-0516 from Tronixlabs is a microwave sensing module that uses Doppler radar technology to specifically detect object movement.
The module has high sensitivity, sensing distance, reliability of the wall, sensing angle, a wide range of power supply and so on. Widely used in a variety of human-induced lighting and burglar alarm and other occasions.
- Using chip RCWL-9196
- Wide operating voltage 4-28V
- Sensing distance 5-9 meter, normally 7 meters, probably can not reach 9M.
- Compared with the traditional infrared sensor PIR, has penetration detection capability
- Blocking time, adjustable distance
- Can output 3.3V power.
