Sensor switch refers to the infrared intelligent induction switch of the human body, which is automatically started when someone passes through the infrared induction detection area. In life, sensor switches can be seen everywhere. Today I'll take you to know more about it.
- Human body sensor switch: it is an automatic control product based on infrared technology. When someone enters the sensing range, the special sensor detects the change of the human body's infrared spectrum and will automatically turn on the load. If the person does not leave the sensing range, the load will continue to turn on; When people leave, the load will be closed automatically after a delay. When people arrive, the light is on, and when people leave, the light is off. It is friendly, convenient, safe and energy-saving, and shows humanized care.
- Infrared sensor switch: usually it is mainly used for automatic control of street lamp switch in public places. The switch is composed of an infrared detection circuit, infrared signal processing circuit, signal output control switch circuit, and power supply circuit; The infrared signal processing integration mainly completes the infrared signal processing. The power supply of the circuit separately supplies power to each subcircuit in the design circuit according to the requirements of each part of the circuit to ensure the stable performance of the circuit. The infrared sensor switch has the advantages of long detection distance, wide application range, strong anti-interference ability, and stable working performance.
Scope of application
The products are suitable for automatic lighting, ventilation, and other purposes in corridors, warehouses, garages, basements, toilets, and other places. Truly reflect the intellectualization of buildings and the modernization of property management.
- Automatic control products based on infrared technology. If the person does not leave and is active, the switch is continuously on; After people leave, the switch will automatically turn off the load after delay. When people arrive, the light will be on and when people leave, the light will be off. It is friendly, convenient, safe, and energy-saving.
- It has a zero-crossing detection function: contactless electronic switch to prolong the service life of the load.
- The application of photosensitive control, switch automatic metering, no induction when the light is strong.
Installation and commissioning
- Since the sensing range of the left and right sides of the switch is larger than that of the upper and lower sides when installing the switch, its positive axis should be perpendicular to the direction of people's walking channel as far as possible, to achieve the best sensing effect.
- Power on after installing the switch. When the ambient light is sufficient, the bulb will flash three times. After one minute, the initialization ends, and the switch enters the monitoring state. Cover the ambient light with an object to make the switch work. If people do not leave and are active, the switch will continue to work; After people leave, the switch will automatically delay closing the load.
- Power on after installing the switch. When the ambient light is insufficient, the switch will directly enter the monitoring state. If people do not leave and are active, the switch will continue to work.
Matters needing attention
The sensor switch works by detecting the presence or absence of infrared rays in the human body. It is generally installed indoors. The false alarm rate of the human body sensor switch is greatly related to the installation position and mode. The installation of human body sensor switch should pay attention to the following points:
?Do not operate with power on during installation.
?Do not use beyond the power range.
?The top-mounted human body sensor switch should not be too high from the ground, preferably between 2.4-3.1 meters. The wall-mounted human body sensor switch can be installed at the position of the original switch for direct replacement.
?When installing a human body sensor switch, it should be far away from heating, air conditioning, refrigerator, stove, and other places sensitive to air temperature change.
?There shall be no partition screen, furniture, large bonsai, or other isolators within the detection range of the sensor
?Do not turn the switch directly to the window to prevent false alarms caused by hot air flow disturbance and personnel walking outside the window.
?The switch shall not be installed at the door, air duct, or other places with strong airflow.
