Microwave Sensor Module  Doppler Radar Motion Detector (HW-M21)
SPECIFICATION
HW-M21 microwave induction module adopts the planar antenna transmitting and receiving. Induction object for moving objects (or car), after induction to the output voltage signal, for active microwave induction, induction Angle of 180 * 180 °, former hemisphere.
Widely used in security monitoring, intelligent systems, control of lamps and lanterns, automatic doors, garage, corridor, roads, etc. Welcome to negotiate!
Features:
1.Is not affected by temperature, humidity, air flow, such as dust, noise, light and dark, strong anti-jamming capability.
2. microwave module is a pattern to launch out, no dead Angle blind area, wide coverage.
3. microwave is reflected more easily in the process of transmission, sensitivity inside will be better, outdoor is a bit poor.
4.can signal through the glass, obstacles such as trees, plastic (this will make the induction distance less)
5. professional design planar microstrip antenna, low power consumption, ROHS, high product consistency.

1.Pay attention to the power supply related requirements, refer to the first one .
2. If anybody there about 1m distance from the module.
3.You shall test the module after 10seconds.
4 It is very sensitive if test indoor. People need stay far away.Test it when no signal output
5 current is very weak when test.Too much current is easy to cause false positives. |
