Specifications:

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.

Warm note:

Power	AC 220V
False Action	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.
Delay time	Default one is 45S，Repeat trigger way
Abs cover	Can custom as client's request
