HW-M09 microwave module

Working Principle:
Microwave sensor module use the planar antenna to transmit according to the  Doppler principle and receive high-frequency electromagnetic waves.And the module detect when a slight movement back fold change wave, which triggers the microprocessor and, ultimately, useful output control signals or control status (on / off). This product is widely used in security monitoring; intelligent control system; lighting appliances (garage, corridor, road and other places use).

Main Feature
1,Strong anti-interference ability. Not influenced by temperature, humidity, airflow, dust, noise, light and dark and other effects
2, It is with wide coverage and no blind spots;
3,The microwave detecting effect during transmission is relatively good: especially if used indoors.The sensitivity or sensing distance will be slightly reduced when used in outdoors due to the different environment. This is a normal phenomenon.
4, Professional design of planar micro-strip antenna, low power consumption, suit with ROHS , with high product consistency.

Warm note:
1, Strictly prohibited to operate in charge to avoid any mistake, such as burn out circuit or get an
electric shock.
2,Avoid installed in the rain, to prevent damage or affect the lifetime.
3: Better install far away from the place of the magnetic field or the conductor to avoid wrong
actions
