Wireless 24GHz mmWave Bio-Radar Sensor for Respiration and Sleep Monitoring
\t\t\t\t\t\t\t\t\tGeneral Description \t\t\t\t\t\t\t
The IR24BDA radar module is a radar detection module based on the millimeter wave Doppler radar theory, which achieves human biological motion perception, human biological perception and human respiration detection.This module is based on the enhanced Doppler radar signal processing theory, and achieves 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.
The 32 array antenna form of this module: wide beam radar module. The wide beam radar module is mainly applicable to the top installation mode to realize radar detection in a large angle range; If it is used for horizontal or inclined installation, it is necessary to pay attention to the occlusion of the actual scene in order to realize the radar detection function in a longer range.

Features
● It realizes the synchronous perception function of moving personnel and static personnel (sitting and sleeping);
● It can keep the detection of static personnel and ensure real-time output;
● It can keep relevant information such as sleep and respiration of sleepers and record relevant sleep time curve information;
● It can quickly output the far and near state of the target range radar;
● It can detect various motion amplitudes and output numerical state in real time;
● It can limit the detection object to persons with biological characteristics (moving or stationary), and eliminate the
interference of other inanimate objects in the environment;
● This module can effectively eliminate the interference of non-living objects, and can also realize the detection of non living moving objects;
● The product supports secondary development and adapts to a variety of scenarios;General UART communication interface to provide general protocol;
● Four groups of I/O are reserved, which can be input and output according to user definition, or simple interface simulation;
● Low output power, no harm to human body;
● It is not affected by temperature, light, dust and other factors, with high sensitivity and wide application fields.

Operating Mode
The beam coverage of IR24BDA radar module is shown in Figure 3.The coverage is a 3D fan-shaped area, horizontal 40°,pitching 40°.
Note: Affected by the radar beam characteristics, the radar operates far in the normal direction of the antenna plane, but the operating distance deviates from the normal direction of the antenna will become shorter.When the radar is installed on the top or obliquely, the radar is affected by the radar beam range and effective radiation space.The scope of action will be reduced, which needs attention when using.
