Sensor is also called induction device or sensor, is a kind of detection device, can receive the information of measured, and the detection to receive further information according to certain rules into electrical signal output, or other forms of information in order to meet the information transmission, processing, storage, display, record and control requirements, usually composed of sensitive components and conversion components. A sensitive element is the part of a sensor that can be measured directly (or in response)
Types of induction switches:
human body induction switch, infrared induction switch, microwave induction switch, electromagnetic induction switch, photoelectric induction switch
Human body induction switch:
it is based on the infrared technology of automatic control products, when someone into the induction range, the special sensor detects the changes in the infrared spectrum of the human body, will automatically connect the load, if the person does not leave the induction range, the load will continue to connect; When the person leaves, the delay automatically shuts off the load. The person arrives criterion the lamp is bright, the person leaves criterion the lamp is extinguish, kind cut convenient, safety saves energy, more show humanized concern. Infrared induction switch: usually used for automatic control of street lights in public places, the switch is composed of infrared detection circuit, infrared signal processing circuit, signal output control switch circuit, power supply circuit several main parts; Infrared signal processing integration is mainly to complete the processing of infrared signal, the power supply of the circuit according to the requirements of each part of the circuit in the circuit of each sub-circuit separately for separate power supply, to ensure the stability of the circuit, infrared induction switch has the advantages of long detection distance, wide range of application, strong anti-interference ability, stable performance
Electromagnetic induction switch:
using the basic principle of electromagnetic induction, generally used in industrial, housing and other circuit control. Electromagnetic induction switch is a contactless switch, can also be used in elevator, elevator and other control systems, to ensure safe operation and accurate stop. It is actually a monostable flip-flop, the circuit is in a steady state when there is no induced pulse signal.
Our infrared hand sweep switches can be used behind mirrors, cabinets and doors.
