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?




  • 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.

Small stature and large angle

Using millimeter wave technology to achieve long-distance and wide-angle sensing range.

6m sensing distance/ 60°
5m sensing distance/ 140°
3m sensing distance/ 180°

8-Speed gap adjustable Interval setting of sensing area

Sensing intervals within a 6-meter sensing range, and the sensing area can be set in intervals, making intelligence so flexible.

45° Folding 360° rotating base

Adjusting the angle is very convenient, and the detection direction is controllable.

Paired with a base, after pasting and fixing, it can still be easily adjusted to the desired detection direction, avoiding damage to the wall caused by secondary pasting.

Installation method

Provide two methods of base adhesive and magnetic suction.
