Intelligent lighting living sensor senses the human body

The intelligent lighting living sensor senses the human body to help the office environment to be green and energy-saving. The lighting management of the office environment has become one of the key elements that immediately affects the office efficiency, and it has attracted more and more attention. Due to the long-term lack of comprehensive energy-saving management system, lack of full-time energy management positions and energy management staff, unreasonable switch installation, unfavorable zoning lighting, etc., a large amount of extravagant waste of energy is caused.

Strengthening the design of intelligent lighting control has become an important part of modern office buildings, because the office environment of modern office buildings not only needs sufficient working lighting, but also needs to create an energy-saving office environment.

The living body sensor is an active detection system integrating the transmitting and receiving systems. The built-in radar transmits electromagnetic waves and receives echoes reflected from walls and objects. Using electromagnetic waves to detect the target, from the target to the electromagnetic wave emission point, the distance, distance change rate (radial velocity), direction, angle and other information, irradiate the target by transmitting electromagnetic waves and receive echoes.

If there is no moving object in the detection area of the live sensor, the echo is constant, and the electronic system will not activate the connected load. Whether the ambient temperature changes or detects the directional movement of a moving object, it can sense instantly. Based on the Doppler effect, it works in the 5.8G frequency band, adopts mature CMOS technology, adopts single-chip integration, and has a flexible and adjustable sensing distance.

The live sensor is widely used in lighting control, human body sensing, motion detection and control and other fields. It filters signals through algorithms and is free from external interference, and meets certification standards such as RED, CE, FCC, and ETL.

The live sensor can be connected to light sources such as fluorescent lamps and energy-saving lamps, and the sensing distance can be adjusted freely to realize detection in all corners of the coverage area. Its delay period can be set. If someone is active in the delay area, the sensor will be activated until the person leaves and enters the delay or sleep state.

When the ambient luminosity is lower than the light sensitivity value set by the sensor, and someone is active in the sensing area, it can intelligently detect the ambient luminosity and whether there is any activity in the sensing area, and the sensor will start the load. When the person leaves the sensing area, the sensor enters the delay state, and after the set delay time period, the sensor will automatically turn off the load.

Within the detection range of the living body sensor, the lights in the office area can be turned on when people come, and the lights can be turned off when people leave, and the power consumption is as low as 40ua, which meets the battery power supply demand!

When the sun is bright, the light is abundant, and the weather is cool, people habitually turn on the lights and fans in the office, and office workers often forget to turn off the lights and fans when they go out to work, which obviously also causes great waste. The technical application of the liveness sensor can implement efficient management by using radar to intelligently control the solar lights and fans in the office, realize that people come to turn on the lights, and people leave the lights off, effectively preventing forgetting to turn off the lights/fans and habits.

According to the traditional method, there are two ways to control the lights in the office corridor. One is to use a double-control switch, but this method is cumbersome and difficult to manage; the other is to keep the lights in the corridor on, which obviously will cause resource waste.

The liveness sensor is used to control the lights in the hallway, which can be used out of the box. This user-friendly control method is used as needed, which not only avoids frequent switching, but also manages it efficiently and avoids wasting energy. Using radar sensors to control the lights between the stairs, you can easily achieve your needs, and effectively adjust the lighting mode according to actual needs, which is efficient, green and energy-saving.

This kind of sensor can also be applied to the parking lot lighting control. The parking lot is usually designed on the negative floor or below. The lighting control is mainly manual control or centralized control. Both of these control methods are not close enough to actual usage and require a lot of manpower to waste energy.

The application of live sensor technology can carry out intelligent control of the parking lot. When the car enters different areas, it will automatically turn on the lights, and when the driver leaves the parking lot, it will automatically turn off the lights, not only the brightness of the lights but also the delay time can be set. Realize the dual functions of intelligence and energy saving, realize green energy saving and environmental protection, and improve the efficient application of energy.
