The IR24SMA radar module is a radar detection module based on the millimeter wave Doppler radar theory, which realizes human biological motion perception and human biological perception. This module is based on the enhanced Doppler radar signal processing theory, and realizes wireless perception of the status of personnel in a specific place through the synchronous sensing technology of Doppler parameters of personnel movement and physiological parameters of personnel.

This module has the following working characteristics
1.  This module limits the detection object to people (moving or stationary), and eliminates the interference of other inanimate objects in the environment;
2.  This module realizes the synchronous perception function of moving personnel and stationary personnel;
3.  This module effectively eliminates the interference of non-living objects, and can also detect non-living moving objects;
4.  The product supports secondary development and adapts to various scenarios;
5.  The output power is small, which does not cause harm to the human body;
6.  This module is not affected by factors such as temperature, light, dust, etc. It has high sensitivity and a wide range of applications.
