Portable embedded infrared sensor

Abstract

The invention provides a portable embedded infrared sensor, which comprises a main body, a limiting plate, two elastic positioning clamps and a detection head, the two elastic positioning clamps are arranged on the two sides of the upper end of the body respectively, torsional springs are arranged at the connecting positions of the upper ends of the elastic positioning clamps and the body, and thelower ends of the elastic positioning clamps clamp the periphery of the body. The limiting plate is arranged at the bottom of the body; the probe is arranged at the bottom of the limiting plate; a control system is arranged in the main body and comprises a chip, an ISP interface, a magnetron relay and a control circuit. According to the invention, long-distance and high-sensitivity induction is realized, the magnetron relay is adopted in the main body so as to solve the problem of noise generated when the inductor acts, and the equipment is convenient to install, fix and disassemble.

Description

technical field [0001] The invention relates to the field of infrared sensors, in particular to a portable embedded infrared sensor. Background technique [0002] Human objects are the most important and active elements in the environment, and the detection of human objects in the scene has always been a hot spot of attention. [0003] At present, most of the people on the market use infrared to sense the movement of the human body to control the light switch or send out high and low level signals. Most of the market uses ordinary mechanical relays. When someone moves, the relay will be closed or disconnected. Ordinary relays The action will inevitably cause environmental noise, especially at night when it is quiet; most of the existing infrared sensors will trigger the mouse or other small pets, so that there will be misjudgment output; although some infrared sensors can adjust the sensitivity, If the sensitivity is increased, it will be triggered by mistake, and if the se...

[0003] At present, most of the people on the market use infrared to sense the movement of the human body to control the light switch or send out high and low level signals. Most of the market uses ordinary mechanical relays. When someone moves, the relay will be closed or disconnected. Ordinary relays The action will inevitably cause environmental noise, especially at night when it is quiet; most of the existing infrared sensors will also be triggered when they sense mice or other small pets, so that there will be misjudgment output; although some infrared sensors can adjust the sensitivity, If the sensitivity is adjusted higher, it will be triggered by mistake, and if the sensitivity is adjusted lower, small movements cannot be sensed at all, so this degree is difficult for customers to grasp
