The RCWL-0516 from PMD Way 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.
