Wireless far-infrared and daylight detector

Abstract

The invention discloses a wireless far-infrared and daylight detector. The wireless far-infrared and daylight detector is characterized in that the detector is composed of six parts, i.e., +3.3 V voltage outputted by a battery portion, a wireless control circuit, a 2.4 G network, an operational amplification circuit, a daylight detector and a far-infrared detector. The +3.3 V voltage of a battery is outputted to the wireless control circuit, the wireless control circuit is in charge of processing received far-infrared detection signals and daylight detection signals, the internal simulation signals are converted into digital signals through a control circuit, the digital signals are then sent to the 2.4 G network for generating wireless signals, and through an antenna, the digital signals are emitted to a terminal illumination electric appliance receiving circuit so as to realize control of light modulation, lamp switching-on and lamp switching-off functions. According to the invention, a far-infrared sensor is adopted so that personnel motion duty ratio is dynamically monitored, and through a wireless transmission mode, a personnel duty ratio control instruction is emitted so that a controlled terminal can realize switching on of a lamp by somebody and switching off of the lamp by nobody.

Description

technical field [0001] The invention relates to the field of lighting, in particular to a wireless far-infrared and daylight detector. Background technique [0002] The wireless far-infrared and daylight detector is a high-tech product with stable performance, which is truly energy-saving and environmentally friendly. It can be said to be a perfect substitute for sound-light control products. It can automatically and quickly open various lamps, anti-theft alarms, automatic doors and other equipment through human body radiation. Especially suitable for medium and high-end hotels, apartments, enterprises and institutions, shopping malls, aisles, corridors, etc. The trigger mode is one-time trigger and continuous trigger. [0003] When changes in the infrared spectrum of the human body are detected, the load is automatically turned on, and the load will continue to be turned on if the person does not leave the sensing range; after the person leaves, the load will be automati...

AI Technical Summary

Problems solved by technology

[0006] 1. Easily interfered by various heat sources and light sources

[0007] 2. The passive infrared penetration is poor, the infrared radiation of the human body is easily blocked, and it is not easy to be received by the probe

[0008] 3. Susceptible to interference from radio frequency radiation

[0009] 4. When the ambient temperature is close to the human body temperature, the detection and sensitivity will drop significantly, sometimes resulting in short-term failure
