Embodiment Construction

[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0030] It should be noted that when an element is referred to as being "fixed" or "disposed on" another element, it may be directly located on the other element or indirectly located on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to or indirectly connected to the other element.

[0031] It is to be understood that the terms "length", "width", "top", "bottom", "front", "rear", "left", "right", "vertical", "horizontal", "top" , "bottom", "inner", "outer" and other indicated orientations or p...

Abstract

The invention relates to the technical field of sensors and provides a sensor. The sensor comprises a fixing tube, a sensing assembly and a movable cover, wherein the sensing assembly is arranged at the end of the fixing pipe, the movable cover is movably connected to the fixing tube, a first opening used for light entering is formed in one end of the movable cover, the sensing assembly is arranged towards the first opening, and the movable cover can move in a retractable mode in the axial direction of the fixing tube, so that the sensing assembly gets close to or get away from the first opening, and thus the light entering angle of the sensing assembly is changed. The sensor is provided with the movable cover capable of moving in the retractable mode in the axial direction of the fixing tube, so that the sensing assembly gets close to or get away from the first opening used for light entering, thus the light entering angle of the sensing assembly is changed, the detecting angle of thesensing assembly can be changed without changing the sensing assembly or replacing the size of a lens, the sensor is simple in adjustment structure and low in manufacturing cost.

Description

technical field [0001] The invention belongs to the technical field of sensors, and more specifically relates to a sensor. Background technique [0002] At present, there are existing PIR (Passive Infrared Detector or body sensor, Passive Infrared Detection) sensors on the market. When the adjustment circuit is fixed, it is equipped with a corresponding lens. The detection angle range is usually fixed. If you want to change the detection angle range, you often need Replace the corresponding lens, or even replace the PIR sensor. Thereby, because of the different requirements of the detection angle range, there are many types of PIR sensors and lenses, which cause various problems for manufacturers, sellers, users, and maintenance personnel of PIR sensors and lenses, such as PIR sensors of various specifications. The quantity of stocking is not equal, resulting in some specifications of PIR sensors are not easy to sell, resulting in a backlog of goods, PIR sensors of best-sel...
