Detect the existence of life in the range of radar antenna by measuring body breathing amplitude and motion amplitude. The motion amplitude information is output through serial port protocol.
The radar has high sensitivity and can measure the change of 0.1mm objects, scan the space changes through electromagnetic waves, find moving objects and the fretting of human breathing chest. To achieve the most fundamental static and dynamic trigger judgment whether there is a judgment.
Because there will be mobile phones, routers, moving objects and other electromagnetic interference in the indoor space, it is easy to misreport someone when there is no one.
Suitable for indoor, no moving object interference occasions; Among pets, metal curtains can cause false positives for radar life detection.
