HW - M09 uses planar antenna is the transmission and reception, as the active sensor. The sensor transmit high frequency electromagnetic wave (10.525 GHz) and receive echo.

HW - M09 detecting changes in the echo inside even small movement. Then microprocessor triggers,executes instruction . Signal can be detected through glass, doors or thin wall.

1.Strong anti-interference ability, stable performance, not influenced by environmental temperature.
2 .Small size, simple installation. Quick response and high sensitivity.
3. Induction distance can also customize, the detection angle is 180 x 360
4 .Radar wave can penetrate non-metallic objects, such as wood, glass, plastic, fabric, etc
