(2) The signal adjustment and comparison control circuit processes and compares the electrical signals transmitted from the photoreceptor assembly. When the two photoelectric signals are similar or identical, the outputs are all low level. When one side is stronger, the stronger side Output a high level and transmit it to the next stage (RS latch).

Working principle of solar tracking system: As shown in Figure 8-10, they are schematic diagrams of the positions of solar panels in the morning, noon and afternoon. The light intensity received by the two photoreceptors is the same, and the solar panel is directly facing the sunlight. As the sunlight gradually shifts from east to west, the light intensity received by the first photoreceptor and the second photoreceptor deviates. The sensor assembly transmits this signal to the tracking controller, and the tracking controller further controls the operation of the motor. The operation of the motor drives the tracking synchronous shaft on the adjustment wheel to rotate until it reaches the first photoreceptor and the second photoreceptor at the upper end of the tracking synchronous shaft. When the intensity of light received is the same, the motor stops working, and the adjustment wheel is rotating, and the solar module also rotates until it stops, so that the solar panel moves with the movement of the sun and always keeps the solar panel facing the sun.
