INTRODUCTION

The IR24DVD1A radar module is based on the frequency-modulated continuous wave system to realize human biological existence perception and human motion perception, continuously record human existence, dwell time, and can notify the gateway through wireless signals to achieve scene linkage. This product is installed on the top of the room. Human function detection is not affected by factors such as temperature, humidity, noise airflow, dust, light, and complete stillness of the human body.  It can be tested with our radar test board(DERADAR-24G), or our converter adapter module(iflabel Link)

It can detect human presence and absence, the motion and the direction of motion, object speed, and detected distance. Meanwhile, it provides the open custom function by offering adjustable underlying parameters for you to adjust detected range, sensing sensitivity, trigger threshold, valid time for states changing, and installation environment.

 

 

 

UPPER COMPUTER SOFTWARE

There is an upper computer software related to this radar, published for real-time acquisition and visualization of radar data, that displays sensing parameters through real-time waveform images which makes data monitoring more clear. Meanwhile, it offers a series of actionable items generated by serial command protocols. Both of them help to increase development efficiency.

 

 

 

FEATURE

● Stationary human detection
● Vital Signs Detection
● 24GHz mmWave radar sensor
● Based on millimeter wave radar technology, realize the function of personnel perception in the radar scanning area;
● Realize the synchronous perception function of moving personnel and stationary personnel;
● Motion sensing maximum distance: 9 meters
● The maximum distance of human static perception: 5 meters
● Antenna beamwidth: horizontal 90°/vertical 60° fan beam
● With scene recognition ability, it can identify people/unmanned people and people's activity status, and output body motion range
● Not affected by temperature, humidity, noise, airflow, dust, light, etc.
● The power of the radar module is less than 0.5 watts and requires long-term power supply work;
● Unmanned to human detection time: within 0.5 seconds
● Time to detect (report) from someone to no one: Automatic detection based on algorithm, typical value is 1 minute

 

 

MAIN FUNCTION

Function points

State change time/function explanation

DP1: Someone/Nobody

No one to someone, report within 0.5s
From someone to no one, output stateless within 1 minute

DP 2 : Sensitivity settings 1 – 10 stops

In the default scene mode, it can support 10 gear adjustments

DP 3 : Scene mode (bed, bathroom, hotel,
bedroom, office, default mode)

Adapt to different scenarios according to the size of the area

DP 4 : No Time Setting

After the environment is unoccupied, output the unmanned status information according to the set time.

 

 

WHAT'S FMCW'S ADVANTAGE

Based on the principle of millimeter wave radar and FMCW ranging technology, the radar only needs to calculate the high-frequency continuous waves emitted to and received from the objects, without any privacy risks. Designed with a low power output, the radar maintains health-friendly working status when it is observed. Thanks to its high immunity against interferences, the output data is less vulnerable to environmental influences like temperature, humidity, noise, airflow, dust, light, etc.

 

 

APPLICATION

● Whole house intelligence
● Smart home appliances (TV, Yuba, security, etc.)
● Office energy saving (air conditioning, lighting)
● Sleep monitoring (sleep curve)
● Home security
● IPC trigger
