Occupancy Sensor module Used for Sensor Light Switch(HW-M08)
HW - M08 microwave 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 is 90degree.Widely used in security monitoring, intelligent systems, control of lamps and lanterns, automatic doors, garage, corridor, roads etc
1).Not affected by temperature, humidity, air, dust, noise, light and dark, not affected by the direction of movement, 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)Signal can pass through the glass, obstacles such as trees, plastic (this will make the induction distance attenuation somewhat)
5) Professional design planar with antenna, low power consumption, ROHS, high product consistency.
We can custom the module as your request,welcome to ask me.OEM is highly welcomed.
4. Warm note:
1)Pls use small ripple of power supply.The power supply voltage must meet the requirements.Also if the power supply current is too small,it can cause false positives or no detecting.
2)When you test the module,pls check if there is anybody within distance 1M.
3)Test In indoor is very sensitive.You shall test when there is no signal output .
4)Please note module output current is very weak, too much drive current is also easy to cause false positives.
5)Can not detect through Metal case
