Fall Detection Sensor Module for elderly- IR24FDA

The IR24FDA mmWave radar sensor module for elderly 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.

The announcement of IR24FDA has significant positive repercussions for the elderly care market. A recent study found that 95% of elderly people want to live alone in later life. Of those elderly people living alone, a third, fall each year. Falls can have serious consequences, with 88% resulting in hospitalization. The tragic fact for many is that many falls go unnoticed for several hours: 60% of people spend 12 hours on the floor and 50% of falls are not reported to the doctors at all. The development of a new, cutting-edge radar fall detector enables these risks to be significantly reduced, empowering elderly people to live independently.

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 real-time monitoring and early warning of falling movements;
3. This module realizes the synchronous perception function of moving personnel and stationary personnel;
4. This module effectively eliminates the interference of non-living objects, and can also detect non-living moving objects;
5. The output power is small, which does not cause harm to the human body;
6. The module is not affected by temperature, light, dust and other environmental factors, has high sensitivity and a wide range of applications.

Measurable range of falling motion

Features:

1. Detection of stationary human body;
2. 24GHz millimeter wave radar sensor;
3. Based on the frequency modulated continuous wave FMCW radar technology, it realizes the two-dimensional area personnel perception function;
4. Realize the synchronous perception function of moving and stationary people;
5. Perception range (circular projection radius): 2～2.5 meters
6. Antenna beam width: 110°
7. Not affected by temperature, humidity, noise, airflow, dust, light, etc., suitable for harsh environments;
8. The output power is small, and long-term exposure does not harm the human body;
9. Nobody to someone: within 0.5 seconds;
10. Someone to nobody: more than 1 minute.




Installation method:

The suggested installation method of this radar module is top installation, as shown below.

Top installation

Main function:

1. Motion detection
2. Slight motion detection
3. Fall detection
4. Action status evaluation
5. Early warning

Human body abnormality judgment method:

1) Record the starting point of the person entering the bathroom and record the stay time;
2) If there is a rapid fall action, the radar will output an alarm signal;
3) After the radar judges the fall, it will continuously output the motion sign parameter signal, if the sign signal is always low, a second alarm is required.

Typical application of bio-radar sensor products:

Typical application scenario 1 — Home & Hotel: 

Typical application scenario 2 — Office & Hospitals & Nursing homes:
