Abstract
The invention discloses an infrared sensor capable of being normally used under a hard light and noise environment and belongs to the field of improvement techniques of electronic component devices. The infrared sensor comprises a tube cap, a photosensitive element, a tube socket and pins, the tube cap is of a cylindrical structure, a window is formed in the top end of the tube cap, an optical filter is embedded in the window, the optical filter is an infrared optical filter, the tube socket is of a cylindrical structure, the optical filter is arranged on one side of the tube socket, the photosensitive element is fixedly connected with high resistors, FETs are arranged between the high resistors and the photosensitive element, and the cylindrical tube cap is connected with the cylindrical tube socket in a covering mode. Compared with the prior art, the infrared sensor has the advantages that design is reasonable, and the structure is simple; the tube cap with the infrared optical filter and the tube socket are adopted, so hard light and noise can be effectively filtered out, the effect of lowering noise is achieved, it can be guaranteed that work of the sensor is not affected under the hard light and high noise environment; meanwhile, the detection distance can be shortened, and detection accuracy can be greatly improved.
Description
Technical field
The present invention relates to electronics devices technical field of improvement, the infrared ray sensor that can normally use under a kind of high light and noise specifically.
Background technology
The infrared sensor principle of work used in the market is: human body sends infrared light and projects on Fresnel Lenses, project again on infrared fileter after lens focus amplifies, project on detection sensitive element after infrared fileter filters out impurities again, light signal is become electric signal and is exported by field effect transistor by detection sensitive element, but conventional infrared sensor cisco unity malfunction under treble noise and sunlight.
In order to well solve the problem, the infrared ray sensor that can normally use under the invention provides a kind of high light and noise.
Summary of the invention
The technical solution adopted for the present invention to solve the technical problems is: the infrared ray sensor that can normally use under a kind of high light and noise, comprise pipe cap, light activated element, base and pin, it is characterized in that: described pipe cap is cylindrical structural, its top has window, described window is embedded with optical filter, described optical filter is infrared fileter, described base is cylindrical structural, its side is provided with optical filter, described light activated element is fixedly connected with high resistant, be provided with FET between described high resistant and light activated element to manage, described cylindrical tube calotte is connected on cylindrical base.
The infrared ray sensor that can normally use under described a kind of high light and noise, it is characterized in that: described pipe cap is cylindrical structural, the internal diameter of described pipe cap is 8mm.
The infrared ray sensor that can normally use under described a kind of high light and noise, is characterized in that: the thickness of described infrared fileter is 0.8-1.2mm.
Beneficial effect of the present invention is:
1) structure of the present invention is simple, easy to operate, is easy to processing;
2) pipe cap with infrared filter and base is adopted, can effectively filter high light and strong noise, serve the effect reducing noise, both can ensure that sensor worked under high light and strong noisy environment unaffected, also can shorten the distance of detection, be that the accuracy of detection improves greatly simultaneously.
