The thermal infrared human body sensor is like the eyes of a cat. It monitors emotions at night. As long as the person is less than 8 meters and the viewing angle is 120°, the monitoring display light can be turned on, and the anti-theft alarm can be connected in series to the corridors of high-rise and multi-story buildings. The switch lights are very safe. Working voltage: AC 180----250V; frequency: 50Hz±10%; load power: 15----200W; load characteristics: incandescent lamp, exhaust fan, alarm; scope of application: all kinds of residential areas, mainly Used in aisle stairs, public corridors, public places that only need automatic lighting in a short time, and connected in series with anti-theft alarm; power supply voltage: 180----250V; service life: ≥100,000 times
An infrared pyroelectric sensor capable of detecting a stationary human body is composed of a lens, a photosensitive element, a photosensitive circuit, a mechanical part and a mechanical control part. Through the mechanical control part (1) and the mechanical part (2), the infrared sensor part (3) is driven to make small left-right or circular motions, and move the position (4), so that the sensor and the human body (5) can form a relative movement . Therefore, whether the human body is moving or stationary, the photosensitive element can generate a polarization pressure difference, and the photosensitive circuit sends out a human identification signal to achieve the purpose of detecting a stationary human body. This infrared pyrosensor can be applied to human body induction control, and realizes the integration of infrared anti-theft and infrared control, and expands the application range of human infrared pyrosensor. It is characterized in that: the lens and the photosensitive element are arranged on the mechanical part.
