Corridor/office building microwave radar wave sensor Doppler detector photosensitive control lighting

Corridor/office building microwave radar wave sensor Doppler detector photosensitive control lighting, microwave radar wave sensor is a moving object detector based on the principle of Doppler effect. It detects whether the position of the object is moving in a non-contact manner, and then acts accordingly. The product has good anti-radio frequency interference ability, is not affected by temperature, humidity, light, air, dust, etc., and can be hung in the air at a height of 3-10 meters. Without affecting its detection function, it can be easily applied to equipment control, ambient auxiliary light source control, underground parking lot, passage lighting and other fields.

Microwave radar wave sensor detects human function:

Working mode: After induction connection, set the delay time, if someone moves, the switch will continue to connect until the person leaves, extending the time.

Smart Delay: After detecting every movement of the human body, the switch automatically delays one cycle, starting from the delay time of the last movement of the human body.

Photosensitive control: According to the external light intensity, control whether the switch works to achieve energy saving effect.

Precautions for adjustment of microwave radar wave sensor:

1. The function of light control is that when the light exceeds a certain intensity, the radar does not sense it. So if you want to sense and control light in brighter places to expand the light, for example, you can turn off the light sense during the day.

2. The selection of each Doppler detector needs to refer to the corresponding space. Large distances are suitable for outdoor or large places, and short-distance sensing is suitable for small spaces.

3. The sensor has a self-test output every time it is powered on. After the delay is adjusted, it will wait for the next induction and work.

It is said that after using smart products, human beings will become more and more lazy and life will become more and more convenient. This is indeed the case, let's take a look at a few smart scene applications:

Intelligent lighting: the light is on when people come, and the light is off when people leave. Range, distance and delay can be set.

Induction automatic doors: avoid contact with public sources of infection.

Intelligent security: Detect moving objects and motion trajectories within the control range.

Smart Medical: Monitor the patient's movements, reactions, every movement, including blinking, breathing, etc.

Microwave radar induction is convenient for our life and travel, and we can enjoy the power brought by technology. Technology changes life, and we can all see it. The application of microwave radar wave sensors can be seen everywhere, such as corridor sensor lights, office doors and so on. The use of microwave radar wave sensors has greatly facilitated our lives. Let's learn about microwave radar inductive detectors.

1. Working principle of microwave radar induction Microwave induction: also known as radar induction, uses the Doppler effect to detect the movement of objects through the microwave emission area, and realizes the control function by detecting the changes in wavelength and frequency before and after the microwave, thereby realizing automatic opening and closing. Function.

2. Sensing objects: The movement of objects (people, cars, animals) can respond quickly. If the detected object is stationary for a long time, the radar will no longer respond and the output will be delayed and turned off.

3. Anti-interference: use 5.8GHz frequency. As we all know, there are many signals of different frequencies in space (for example, the 4GHz signal of a mobile phone is similar to the human body induction signal), which can effectively prevent signal interference and reduce errors.

4. Strong applicability: microwave radar sensors can penetrate ordinary glass, wood, walls, and are not affected by any temperature, humidity, dust and other harsh environments; widely used in indoor places, such as study, corridor, garage, warehouse, basement, Elevator entrances, doors, etc. Suitable for controlling loads, such as ordinary ceiling lamps, fluorescent lamps, LED lamps, etc. , almost all lighting can be used, small size, no space, easy installation.

5. Energy saving and environmental protection: The microwave radar wave sensor has low power consumption and starts at zero level, which maximizes the service life of the sensor. The intelligently controlled automatic switch can only work when it is really needed, which helps to save energy and reduce consumption, and is more environmentally friendly.

6. Advantages compared with similar products:

Touch switch control and panel switch control all require manual touch motion control, which is very inconvenient at night;

The voice-activated induction control is the most susceptible to the influence of the external environment, it is easy to trigger the lighting by mistake, the induction is not sensitive, and sometimes it is necessary to deliberately step on the floor to make a sound, especially it is not suitable for the external environment;

The principle of infrared induction control is that the sensor detects the temperature of the human body and compares the characteristic temperature of the sensor to control the lamp; the disadvantage is that the sensing angle is small, when the ambient temperature changes, the sensitivity is reduced, and even the lighting is accidentally touched.

Compared with common lamps, the microwave sensor control mode completely avoids touch switch control. Panel switch control, voice control, induction control, infrared sensing, etc. Its advantages are: wide coverage and strong anti-interference ability. High detection sensitivity, adapt to different environmental conditions, completely liberate hands, perceive the movement ability of objects at a distance, adjust brightness, and use in different environments.

Our company has been focusing on the research and development of space sensors for many years. Microwave radar wave sensors are mainly used for breathing, movement, micro-detection and switch applications.
