Human Presence Sensor Radar Sensing Related Information and Product Features

Human presence sensor radar sensing related information and product characteristics, human presence sensor is based on Doppler effect, using advanced planar antenna, can effectively suppress the interference of high harmonics and other clutter, high sensitivity, strong reliability, safety and convenience, Intelligent and energy-saving, with complete functions, it can bring various lamps and lanterns.

Human presence sensor principle:

Electromagnetic waves are emitted through a planar antenna. When the moving object enters the electromagnetic wave environment, the waveform is reflected and folded, the planar antenna receives the feedback waveform, and the subsequent circuit detects the trigger signal. So as to play the role of opening and closing.

The main reason why the radar sensing of human presence sensor is widely used is to make full use of light-like properties, penetrability, and long sensing distance.

Photolikeness: Refers to the ability to propagate and concentrate more like light than radio waves with lower frequencies;

Penetration: Compared to infrared, it is more internal when irradiating the medium.

Induction distance: up to 5-50 meters.

Human presence sensor radar sensing characteristics:

1. Intelligent induction: When someone enters the detection range of radar sensing, the detector lights up the light, and when someone leaves the detection range, the light will automatically turn off. It can automatically identify day and night.

2. Intelligent delay: After the human presence sensor radar sensing detects each activity of the human body, it will automatically delay a period, and the delay time of the last human activity will be the starting point.

3. How it works: Once connected, radar sensing will connect during a delay until people leave and extend the time.

4. Photosensitive control: According to the external light intensity, control whether the human presence sensor works or not, so as to achieve the effect of energy saving.

5. Compared with infrared products: the radar sensing distance is farther, the angle is wide, and there is no dead zone. It can penetrate glass and thin sheets. Depending on the power, it can penetrate walls of different thicknesses and is not affected by the environment, temperature and dust, and the sensing distance will not be shortened. Radar is an ideal replacement for infrared switches.

Human presence sensor radar sensing: can pass through most objects, hidden in lamps or other places; controllable energy-saving lamps and incandescent lamps. It has a fast response to the movement of the object, and is especially suitable for the detection of fast-moving objects.

Human presence sensor uses Doppler radar technology to detect moving objects, also known as Doppler motion sensor, or human body sensing intelligent detector, with high sensitivity. The sensing distance is long. High reliability. Large sensing angle. Wide supply voltage range, widely used in burglar alarm and lighting industry. The multi-function presence sensor supports mixed detection of movement, micro-motion and breathing, and realizes the perception of presence; the dimming can also be set through the remote control, and the operation is simple; in the environment supplemented by natural light, it can also achieve constant illumination, maximizing energy saving and Optimum comfort.

The human presence sensor integrates a low-power system-level module, which is easy to use and can be applied to various projects. It is an ideal choice to replace ordinary motion sensors. It can detect objects within the range of motion.

The human presence sensor radar sensing has achieved a breakthrough in the traditional sense, realizing real presence sensing, and the detection will not be disturbed by fans. It is widely used in offices, conference rooms, classrooms, living rooms and warehouses by many enterprises and families. It is the product of choice for intelligent energy-saving users!
