Microwave sensor switch manufacturers Micro-motion sensor is more suitable for home lighting proximity switch working principle analysis

Micro-motion sensors are more suitable for the analysis of the working principle of home lighting proximity switches. In the eyes of many people, lighting equipment only plays the role of lighting, but the installation of lighting equipment with microwave induction switches will change the traditional law of life. When you get home from get off work at night, you need to manually turn on the lights to light up the entire room. Of course, there were also bad experiences. I am sure you have had this experience in your daily life:

Get up in the middle of the night and want to go to the toilet, but stretch out your hand in a dark room, you can't even see your fingers, you may stumble, fall, and finally turn on the light in the dark, the light is too dazzling, and consciousness wakes up immediately.

Breastfeeding mothers feed at night and turn on the light, afraid that the child will be awakened by strong light, so do not turn on the light, even adults do not like too strong light in the middle of the night, which will affect sleep awareness.

It is a problem for the elderly to turn on the lights in the dark at night, and an accidental fall may be a big deal!

In order to solve these problems, the micro-motion sensor switch products of microwave sensor switch manufacturers have entered people's field of vision, and can carry out intelligent sensing lights. Micro-motion induction lamps and human body induction lamps are the more popular home decoration products in the past two years, and the demand for such lamps is no longer small. At present, in the community, corridors no longer use traditional switches to control lighting equipment, but often use human body induction lights to control the switches of lighting equipment through induction.

Human body perception is a new technology that uses the principle of reflected electromagnetic waves to detect the information of human activities. It is a product specially designed to detect and detect human activity information. When a person enters the detection range of the microwave induction switch, the detection module will output a high-level pulse signal or a high-level delay signal. The output detection pulse or delay signal can directly drive LED lighting and LED lighting. The switch is mainly composed of a radar module and a dedicated monolithic integrated circuit, which achieves the effect of people turning on the lights and people turning on the lights.

In order to improve the actual use effect, the human body micro-motion sensor can be used together with the pedestrian-sensing ultrasonic sensor. The infrared energy released by the human body detects the presence of a human body in the sensing area, the LED indicator lights up, and the ultrasonic detection sensor controls the ultrasonic emission. The ultrasonic sensor transmits the distance signal to determine whether the human body existing in the sensing area is a micro-moving human body. If the human body in the detection area is a micro-moving human body, it is determined that the control LED indicator is on; if the human body in the detection area is not a micro-moving human body, it is determined that the LED indicator is off. The advantage is that it can effectively detect the micro-moving human body and is more practical.

Micro motion sensors are leaders in motion detection. It not only supports the detection of people's light movement, but also supports the detection of small movements of the human body in a stopped state. Adopt filtering technology to solve the problem of large deviation of light sensitivity value in sunny, cloudy and rainy days. It has strong environmental adaptability and can resist false triggers such as mosquitoes, birds, and leaf floating.

Our company has a history of 20 years in the research and development of space sensing. Various sensor products have been exported at home and abroad and enjoy a certain reputation in the world. It is an advanced enterprise in microwave sensing technology in China.

Proximity switch working principle and five types of detection analysis. The currently used types include limit switches, limit switches, and micro switches. Below are the proximity switches. As the name implies, as long as the proximity sensor is used, the command operation can be performed to realize the switch function of the device. The detection body is close to the sensing surface near the switch, it can send out instructions, can the detection body be used at will? The specimen cannot be used arbitrarily. The types of proximity switches are mainly different and therefore the requirements for detection are also different.

Now let's talk about five different types of proximity switches:

Sensors required for electromagnetic inductive proximity switches such as magnetic switches are magnetic metals. Electromagnetic induction type proximity switch operation using permanent magnets. For example, as long as a permanent magnet is placed on the valve switch, magnetic switch and piston rod, and the magnetic switch is pasted on the valve cylinder, the piston rod will move with the permanent magnet. When the detection distance range is reached, an action command will be issued.

The high-frequency vibration type proximity switch can work as long as the detection body is a metal material.

Capacitive proximity switch with large detection range. All kinds of conductors and non-conductors are very good, whether it is solid or liquid, the detection object can be its detection object.

Ultrasonic type proximity switch. The logic command can only occur when the ultrasound has to come back. It can be seen that, unless ultrasonic waves are absorbed, this type of proximity switch requires a detection body.

The working mode of the photoelectric proximity switch is similar to that of the ultrasonic proximity switch. The former requires the detection body not to transmit waves. Likewise, the detector body of the photoelectric proximity switch cannot transmit light.

Proximity switches are widely used in life industrial control systems, but they can be used flexibly to participate in automatic control in various industries. Such as daily life, hotel, security, anti-theft, etc.
