Abstract

The invention discloses a sun tracing photoreceptor which can directly detect the position of an optical source and is used for the mechanism of a solar battery for tracking the sun. The photoreceptor includes a sensitization apparatus and a control circuit. The sensitization apparatus includes a shell (8) of the sensitization apparatus and a photoresistance(1); the photoresistance is arranged on the bottom plate of the bottom plate shadow area of the shell and at the side tangent with the boundary (5) of the shadow area and far away from a window; two extension lines (7) of the photoresistance penetrate from the bottom plate of the shell (8) of the sensitization apparatus to form the connection between the apparatuses of the control device; one line (7) of the photoresistance is connected with the cathode of a power (13); one end of a not gate (17) is connected with one end of a relay loop (J); the other expansion line is connected with one end of an adjustable resistance (15); the other end of the not gate (17) is connected with the other end of the relay loop (J); the other end of the adjustable resistance (15) is connected with the anode of the power (13) by a switch (14).

Description

Technical field [0001] The invention relates to a photoreceptor used to sense the position and changes of the sun or other light sources. Background technique [0002] Currently, sensing devices used to track the sun usually use power comparison or voltage comparison to identify the position of the sun and its changes. However, the structure of the comparison circuit is usually more complicated, and more devices are used, which makes it difficult to control the stability and discrimination of the system, and also causes an increase in manufacturing costs. Summary of the invention [0003] What the present invention aims to solve is to overcome the problems existing in the prior art and provide a sun tracking photoreceptor. [0004] The technical solutions adopted by the present invention to solve its technical problems are: [0005] A sun tracking sensor includes a photosensitive device and a control circuit. [0006] The photosensitive device includes: a photosensitive device h...
