10GHz Microwave Radar
Sensor Module

Model:
RADAR10GATDUL 10.525G

WENSHING Electronics will release the RADAR10GATDUL (Doppler) 32meters long-distance radar human movement detection module series in December 2022. RADAR10GATDUL is the legal ISM band of 10.525GHz.

The infrared probe of the passive PIR pyroelectric sensor is emitted by detecting the body temperature. The disadvantage is that it is easily interfered by various heat sources and light sources, and the penetration is poor. Environmental conditions, and the distance is short, only 2-3 meters.

Radar detection cannot achieve energy-saving functions due to its power consumption, and the detection distance is not far away, and the installation density and quantity are too large, resulting in high cost.

WENSHING Electronics has improved the problems of PIR misjudgment and short distance, overcomes the shortcomings of radar power consumption, and saves user costs. It has developed RADAR10GATDUL, which has an ultra-low operating voltage of 2.1V and an ultra-low current of 98uA. It only needs 0.0002W power consumption for normal detection, up to 32 meters to detect ultra-long distance.
