Wide-angle 220V microwave doppler radar switch sensor module for Automatic Doors M21

Product Description




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!




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.Can modify the module according to your design.





Microwave modules can be widely used in security monitoring, automatic doors, automatic lights, power automatic switch, automatic street light switches, industrial automation control, indoor and outdoor security systems, automatic door control switch, ATM automatic teller machines, automatic recording control system place and so on.
