Solar Tracking Module Automatic Tracker Single Axis Solar Tracking Module Search Light Solar-powered Trace BoardINTRODUCTIONProduct name: uniaxial light source tracking boardVoltage: DC 5-5.5VCurrent: less than 1.5AInterface: power supply (+ -), motor MPrinciple: use an occlusive object on the photosensitive resistor.When the light strikes the occlusive object and forms a shadow, when the photosensitive value on one side is different from that on the other side, control the motor to find the balance point, namely the light source center.The power supply USES A dc power supply of 5-5.5v, and the current of 1.5a is enough. Motor use speed motor, the slower the better. When the power supply is 5V, no load is taken and the speed is stable. If the motor speed is too fast, it may cause that the motor does not align with the center of the light source and swings from side to side, but does not dither. This circuit adopts the short delay of anti-dither. The connection between the motor and the plate is not divided into positive and negative poles. During the test, if the motor is found to rotate reversely to the light source, the motor line shall be switched. The power supply must be regulated 5-5.5v, and cannot be directly connected to solar panels. The accuracy of tracking Angle is related to the position of probe, Angle and size of shading object. If you are not on time, please check by yourself. As shown in the figure, the photosensitive probe is on the same plane, and the small solar panel seat shade is used above. When the light intensity of the left probe is greater than the right side, the motor turns left until the two probes balance the value. The size of the shade is related to the angular accuracy of the light source. It's best to cover both probes at the same time. The tracking angle accuracy is related to the probe placement position, angle, and shade size.
