The principle of radar induction is Doppler effect principle, which has the characteristics of long sensing distance, large angle, high sensitivity, penetrating non-metallic materials, and is not affected by environment, temperature, dust, etc.

The infrared induction is to trigger the work of the follow-up circuit by receiving the infrared emitted by the human body through the pyroelectric element (the human body has a constant temperature, so it will send out the infrared of a specific wavelength). Its induction distance is general, the angle is small, and it is greatly affected by the environment, temperature, ash, etc., and the detection infrared sensor head needs to be exposed, which is not convenient to install.

Radar inductive switch, also known as microwave induction switch, is based on Doppler effect and adopts the most advanced planar antenna, which can effectively suppress the interference of high-order harmonic and other clutter, with high sensitivity, strong reliability, safety and convenience, intelligent and energy-saving. It is the first choice for intelligent building and modern material management.

1. Intelligent sensing: when someone enters the detection range of the product, the microwave detector will work and light up the lamp. When the person leaves the detection range, the lamp will automatically turn off. It can automatically identify day and night.

2. Intelligent time delay: the switch will automatically postpone a cycle after detecting each activity of human body, and take the delay time of the last human activity as the starting point.

3. Working mode: after the induction switch is turned on, in the delay period, if there is human activity, the switch will continue to turn on until the person leaves and the time is postponed.

4. Photosensitive control: according to the external light intensity, to control whether the switch works, in order to achieve energy-saving effect.

Compared with infrared products: the radar switch has longer sensing distance, wide angle, no dead zone, and can penetrate glass and veneer. According to different power, it can penetrate walls of different thickness, and is not affected by environment, temperature and dust. Under the condition of 37 ℃, the sensing distance will not be shortened. Radar switch is an ideal replacement product of infrared switch.

Application scope: corridor, corridor, toilet, basement, garage, warehouse, monitoring and other energy-saving automatic lighting places.
