Product introduction

Microwave motion sensor module consists of a microwave motion sensor and a sensor
controller board in which the IF signal from the sensor is further processed to determine the motion
events. The high sensitivity of the sensor module is due to the multi-stage amplification circuit on
the controller board. Based on the detection of the backscattered Doppler signal, HP300 can detect
any motion event in the effective power range. In addition, the backscattered Doppler signal can be
sampled and then transmitted via UART interface to other advanced MCU or DSP boards for
further processing. For example, the motion velocity can be obtained by the calculation of the
Doppler frequency using FFT signal processing. The relay output of the sensor controller board can
be used to drive the alarms or lamps easily.

The microwave motion sensor module offers a number of advantages over alternative
technologies such as ultrasonic, optic, magnetic switch, or infrared sensors in the senses of greater
range, and better penetration, etc.
