Problems solved by technology

[0003] As far as the principle is concerned, the traditional passive infrared thermal release human body sensor switch works through the infrared rays emitted by the sensed human body, but the passive infrared thermal release human body sensor switch that we are widely using now can only sense "on" by the human body. Instead of human body induction "off", the passive infrared pyrolysis human body induction switch that we widely use now can only use the delay effect of the capacitor to realize the "off" function. Only by "moving" can it keep its "open" action. Under this condition, the scope of use of passive infrared pyrolysis human body induction switch is greatly limited.

[0004] There is also an infrared pyroelectric human body sensor switch, which uses a mechanical device to make the Fresnel lens in front of the infrared pyrosensor move relative to the infrared pyrosensor, or add a movement between the Fresnel lens and the infrared pyrosensor None of these methods can really realize the function of "open when people come - close when people leave"

[0005] Although the active infrared human body induction switch can realize the instant switch function of human body induction of "when people come and turn off", its scope of action is usually limited, and it can only cover a very limited area in its optical path. It can sense the existence of the human body within a certain range, so as to realize the function of "on" or "off". At the same time, this kind of human body sensor switch also has many problems such as poor anti-interference ability and high energy consumption.

These characteristics make the scope of use of the active infrared human body sensor switch subject to many restrictions;

[0006] The active microwave detection human body induction switch using the principle of microwave interference has a microwave emission source that emits microwaves continuously. It uses the reflected microwaves to complete the detection and judgment of the position of the human body (including objects) and realize the corresponding "open" or "Off" function, this device can also use the Fresnel principle to detect and judge moving human objects (including objects) to achieve the corresponding "on" or "off" function, using the active principle of microwave interference Microwave detection human body induction switch has many disadvantages such as high energy consumption, many faults, and microwave pollution to the environment, which is not conducive to popularization

[0007] The human body induction switch using the capacitive effect is usually used within a range of about 2 meters. The human body sensor switch with capacitive effect has the same disadvantages, so it is difficult to popularize and apply
