Illumination sensor for smart home

Abstract

The invention relates to the technical field of illumination sensors, in particular to an illumination sensor for a smart home. The illumination sensor comprises an instrument box, a circuit board, a top disc, a control disc and a transparent disc; the circuit board is fixed in an inner cavity of the instrument box; the instrument box is in a circular plate shell shape with an opening in the bottom surface of one side, the opening end is fixedly plugged with the annular plate-shaped top disc; an annular groove is formed in the side, back to the instrument box, of the top disc; the annular-plate-shaped control disc is arranged in the annular groove in a matched mode; and the transparent disc is arranged in the middle of the control disc. According to the structural design of the sensor, after the illumination sensor senses that people pass through the monitoring range of the illumination sensor, household equipment controlled by the illumination sensor is triggered to work, and convenient life experience is brought to people; and in addition, the sensor can automatically start ash wiping and cleaning work on the transparent disc, it is ensured that the transparent disc is clean and tidy, and the sensitivity of a photosensitive component in the transparent disc to light sensing is improved.

Description

technical field [0001] The invention relates to the technical field of light sensors, in particular to a light sensor for smart homes. Background technique [0002] The light sensor of the smart home in the prior art belongs to the photosensitive element and the semiconductor sensitive element and is widely used in the smart home. It senses the light changes in the external environment through new energy semiconductor photosensitive devices to trigger the control of other household equipment. The light sensor is set on the wall or other supporting objects that people pass by. After the people pass by, the sensor The semiconductor photosensitive element in the box will work when it senses the change of the environment. In order to improve the sensitivity of the entire light sensor, the components used for sensing are generally suspended. Since the sensitivity and accuracy of the light-sensing semiconductor element are directly related to the ambient light it can feel, they a...
