User Manual

◆ 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.
1. Overvieww
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 element 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.
The radar module has the following working characteristics::
