24GHz Millimeter Wave Radar Human Presence Detection Sensor
Roof mounted

Static human body presence recognition

Ceiling concealment 丨 6 Meters sensing distance
Intelligent linkage 丨 8-Speed gap adjustable

The Linptech radar human presence sensor ES1 is based on 24G microwave technology, actively detecting subtle movements, such as chest micro movements caused by human breathing and local micro action lights of the human body, thereby achieving recognition and distance positioning of static human bodies.

Compared to traditional infrared human body sensors, it can effectively avoid the situation that the light automatically be off when there is no motion.

	Radar human presence sensor	Infrared (PIR) human body sensor
Induction mechanism	Doppler radar sensing principle (active detection)	Principle of Pyroelectric Infrared Induction (Passive Radiation)
Action sensitivity	Detect human heartbeat, breathing, micro movement, and movement	Only human movement and close range micro movements can be detected
Environmental temperature impact	No temperature effect	Sensitivity decreases when the temperature rises close to the human body
Application environment	Not affected by heat sources, light sources, or airflow interference	Easy to be disturbed by heat sources, light sources, and airflow
Penetration ability	Permeable fabric, plastic, glass lamp insulation materials	Only partially transparent plastic can be penetrated
Does the sensor detectthe distance?	Yes	No

Feature

24GHz millimeter wave radar sensor - detect human presence and absence, the motion and the direction of motion, object speed and detected distance.
Highly configurable-adjust detection range, sensing sensitivity, trigger threshold, valid time for states changing, and installation environment.
Human motion perception maximum range: 6 meters.
With scene recognition ability, identify human presence/absence and human activity state, output body motion amplitude.
High immunity against interferences: Output data independently of environmental influences like temperature, humidity, noise, airflow, dust, light.
Long power supply, the radar module power is less than 0.5 watts.
