Abstract

The invention discloses a sensor and a sensing system for automatically judging entering and exiting of a human body, comprising a shell and an electronic base board, wherein a sensor is arranged at the surface, facing the inside of the shell, of the electronic base board; a window is arranged on the side wall, facing the sensor, of the shell; a Fresnel lens located between the sensor and the window is arranged in the shell; the sensor internally comprises two sensing elements which are distributed along the human body entering and exiting direction and are used for detecting the intensity ofhuman body infrared radiation and outputting a radiation detection signal; a controller electrically connected with the sensor is arranged on the electronic base board; the controller is used for storing and analyzing the radiation detection signal; the window can control the recognition area of the sensor to a certain scope, so that a person can be detected by the sensor only when reaching such scope; in order to be adapted to different application occasions, the detection area of the sensor is changed by changing the shape of the window, and therefore, the humanization degree is high, and the application scope is relatively wide.

Description

technical field [0001] The invention relates to the technical field of sensing, more specifically, it relates to an inductor and its sensing system. Background technique [0002] In order to realize humanized service, an inductive announcer is usually installed at the door of some service stores, which automatically broadcasts the voice of "Welcome" when it senses that someone is approaching, so as to achieve the double function of reminding someone to enter and welcoming guests. The induction announcer includes the induction element and the Fresnel lens covered outside the induction element. The Fresnel lens is mostly made of polyolefin and other materials, and can be classified according to the optical design or structure. It has three functions, one is focusing The second is that the moving object in the detection area can generate a changeable heat release infrared signal on the passive infrared (Passive Infrared, PIR) in the form of temperature changes; the third is the...
