Description

Specifications:

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 negotiating!

Features:

1. Is not affected by temperature, humidity, airflow, 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, or plastic (this will make the induction distance less)
5. professional design planar microstrip antenna, low power consumption, ROHS, high product consistency.
