Existing human body inductive sensor

Abstract

The invention discloses an existing human body inductive sensor, which comprises an infrared sensor probe, a bearing part for bearing the infrared sensor probe, a motor, a rotary baffle plate and a Fresnel lens, wherein the infrared sensor probe is arranged under the Fresnel lens; the motor is connected with the rotary baffle plate; the rotary baffle plate is arranged between the infrared sensor probe and the Fresnel lens; and the motor is used for driving the rotary baffle plate to rotate so as to enable the infrared sensor probe to be alternately changed between a shielded state and a non-shielded state. The existing human body induction sensor can detect and sense a static human body, so that induction is more accurate, and better use experience is brought to people.

Description

technical field [0001] The invention relates to the field of sensors, in particular to a presence-type human body induction sensor. Background technique [0002] With the development of society, people's requirements for the quality of life are getting higher and higher. In order to make life more convenient, people are increasingly introducing lighting equipment in various occasions, and lighting energy consumption is also increasing. In order to avoid energy consumption Intelligent lighting control is increasingly used in people's daily life; among them, pyroelectric infrared sensors are increasingly used in intelligent lighting control, but pyroelectric infrared sensors can only work passively , cannot detect stationary objects. When people are in a stationary state indoors, pyroelectric infrared sensors cannot detect the existence of human bodies, which brings inconvenience to people; in order to solve this problem, there are basis The human body detection sensor made o...

[0002] With the development of society, people's requirements for the quality of life are getting higher and higher. In order to make life more convenient, people are increasingly introducing lighting equipment in various occasions, and lighting energy consumption is also increasing. In order to avoid energy consumption Intelligent lighting control is increasingly used in people's daily life; among them, pyroelectric infrared sensors are increasingly used in intelligent lighting control, but pyroelectric infrared sensors can only work passively , cannot detect stationary objects. When people are in a stationary state indoors, pyroelectric infrared sensors cannot detect the existence of human bodies, which brings inconvenience to people; in order to solve this problem, there are basis The human body detection sensor made of the principle of life detector, but the price is relatively expensive, and there is also the problem of insensitivity of detection, which cannot realize efficient and effective detection of stationary human body
