Infrared sensor is a sensor that uses the characteristics of infrared radiation produced by objects to realize automatic detection. Infrared ray is getting old again.
It is called infrared light. In physics, visible light and invisible light, radio and infrared light are all electromagnetic waves, but their wavelengths or frequencies are different.
Principle of infrared sensor? Function of infrared sensor
Principle of infrared sensor
According to the principle of infrared reflection, when a human hand or a certain part of a human body is in the infrared region, the infrared emitted by the infrared emitting tube is reflected to the infrared receiving tube by the human hand or the human body, and the signal processed by the microcomputer in the integrated circuit is sent to the pulse electromagnetic valve, which opens the valve core to control the head to discharge water according to the specified instructions after receiving the signal; When the human hand or body leaves the infrared sensing range, the electromagnetic valve does not receive the signal, and the valve core of the electromagnetic valve is reset by the built-in spring to control the water to turn off.
Function of infrared sensor
Infrared sensors actually have many functions, although you may not have heard a lot. For example, it can effectively prevent water pipes from freezing in cold winter, and the system automatically enters the intelligent control system in a digital way to adjust the delay quickly and accurately. It only takes a few seconds to change the program parameters, and intelligent fuzzy control can achieve the best flushing effect according to the number of users and waiting time.
The infrared sensor in the toilet has many practical functions, although you may not hear many. For example, it can effectively prevent water pipes from freezing in cold winter, and the system automatically enters the intelligent control system in a digital way to adjust the delay quickly and accurately. It only takes a few seconds to change the program parameters, and intelligent fuzzy control can achieve the best flushing effect according to the number of users and waiting time.
Infrared sensor installation
The invention relates to a trough public water-saving device, which is characterized in that an electromagnetic valve is installed on the original automatic water tank at the water inlet, and an infrared sensor is installed on the ceiling at the entrance of a toilet or urinal. The infrared sensor automatically detects on the spot, and sends the detected signal to the control box A. The microcomputer of the control box sends out an instruction to control the solenoid valve to fill the automatic water tank, and the automatic water tank is flushed after being reserved by the program. When someone enters the public toilet, the infrared sensor will start the above operation. If no one enters the public toilet, the whole system will stay put and never flush, thus achieving the effect of automatic hygiene management and water saving.
Microcomputer can control, intelligently manage and automatically sense. When there are many people, they will rush more, and when there are few people, they will rush less. When no one is around, you won't flush. Suitable for various occasions, digital adjustment and adjustment of program parameters only take a few seconds. Microcomputer control technology does not need batteries, and the program will not be lost under any circumstances. Is a high-tech enterprise integrating research, design, development, production and sales. Its design service life is more than five years, and it can work normally whether it is high temperature or freezing for more than ten degrees in summer, and it is suitable for products in various harsh environments. The installation height is more than 2.4 meters, which can not only avoid man-made damage, but also avoid personal contact.
