Human Presence Sensor Module - IR24VDA

INTRODUCTION

The IR24VDA 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. It can be tested with our radar test board(DERADAR-24G), or our converter adapter module(iflabel Link)

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. This module is not affected by factors such as temperature, light, dust, etc. It has high sensitivity and a wide range of applications.

FEATURE

●  Detection of stationary human body;

●  24GHz millimeter wave radar sensor;

●  Based on the frequency modulated continuous wave FMCW radar technology, it realizes the two-dimensional area personnel perception function;

●  Realize the synchronous perception function of moving and stationary people;

●  Maximum distance of motion perception: ≤13m;

●  Maximum distance of slight motion perception: ≤5m;

●  Maximum distance of human perception: ≤3m;

●  Antenna beam width: horizontal 90°/vertical 60°;

●  Possesses the ability to recognize scenes, identify someone/nobody, detect personnel activity status, and output movements signal;

●  The output power is small, and long-term exposure does not harm the human body;

●  Nobody to someone: within 0.5 seconds;

●  Someone to nobody: more than 1 minute.
