The microwave sensor uses the Doppler principle to transmit and receive high-frequency microwave signals with a flat antenna to sense the relative movement signals of objects (such as people, cars, etc.) within the coverage. After the signals are amplified and intelligently identified and processed by the single chip microcomputer program, the high and low signal levels are output to drive the relay switch to control the on and off of the load lamps;
Compared with infrared products, the radar switch has longer sensing distance, wide angle and small dead zone. It can penetrate glass and thin wood. According to different power, it can penetrate walls of different thickness without being affected by environment, temperature and dust. When the temperature is above 37 degrees, the sensing distance will not be shortened, the temperature is changing, and the sensing distance remains unchanged. Radar switch is an ideal replacement product of infrared switch.
1. Intelligent sensing:
1> When someone enters the sensing detection range (within 16m in diameter), the load lamp will turn on; when someone leaves through the sensing detection range and the countdown of the set delay time ends, the load lamp will turn off automatically.
2> When a person enters the sensing detection range and the load lamp has been turned on, if the person stays within the sensing detection range, before the countdown of the set delay time, as long as the person is in a moving state, the sensor will drive the load lamp to turn on continuously until the person leaves and the countdown of the set time is over, the load lamp will turn off automatically.
2. Intelligent identification:
1> In short, this product can be set to be off during the day and on at night when there are people; it can also be set to be on at any time as required.
2> This product has a variety of light setting options, which can be adjusted by customers according to their needs to meet the lighting needs of different light environments.
3. Anti interference:
As we all know, there are many signals with different frequencies in the space (such as 3GHz signal of mobile phone, 2.4GHz signal of WiFi, 433khz signal of TV remote controller, acoustic signal, etc.), and some signals are consistent and similar to human body induction signals. Our products can intelligently identify useful human body induction signals, prevent mistriggering lighting of other interference signals, and ensure product reliability.
