The human body induction switch has three wires (live wire output) (live wire input) (zero wire input), while my home appliance has only two wires. How to connect them?

Two live and neutral inputs of the power supply. The live wire output is connected to one foot of the light bulb. The other end of the bulb is connected to the zero line.

The human body is an emitter of infrared rays with a specific wavelength. After the infrared sensor detects the change of infrared ray, amplifies and selects the frequency, it can push the appropriate load. This is the human infrared automatic switch. This detection technology is more sensitive and accurate than ultrasonic, dumb and microwave methods.

It is required that the signal amplification and processing circuit of PIR pyroelectric human infrared sensor has high sensitivity, which can accurately distinguish biological and abiotic movements, so as to minimize the misoperation rate. And has small volume and low self consumption.

This switch, which consists of pyroelectric infrared sensor and special monolithic integrated circuit, turns on the light when people leave, and turns off the light when people leave. The installation is simple, and the 86 panel switch can be directly replaced without replacing the power cord.

Extended data:

Human-induced switches are often used in stairs, walkways, toilets, elevators and many other ordinary public places. When the human body enters the sensing range of the switch, the microcomputer system of the switch can sense the infrared pyroelectric change of the human body movement, automatically turn on the lighting at the same time, and automatically turn off the lighting after sensing the human body leaving and delaying the preset time. Light a lamp for you in the dark:

1, used in meeting rooms, office areas, bathrooms and basements. It can make people turn on the lights and turn off the lights, which greatly avoids waste, saves energy for you and saves you the pain of forgetting to turn off the lights.

2, used for disinfection room. When people come, they automatically turn off the disinfection equipment, and when people leave, they automatically turn on the equipment. Escort for health.

3. Used in hotels, guesthouses, etc. Instead of the existing plug-in card to get electricity, it can also monitor the room dynamics. When people come, they will automatically turn on the power, and when people leave, they will automatically turn off the main brake. Full of humanity.
