BTF 5-5.5V Light Source Tracking Board Solar Tracking Module Solar Automatic Tracker

5-5.5V Light Source Tracking Board Solar Tracking Module Solar Automatic Tracker Features: brand new and high quality The solar panel automatic tracking sensor has two ports, including power +- and motor for M. Packing list: 1 module, 2 probes. Principle: Place a shielding cover on the photoresistor. When the light hits an obstacle and forms a shadow, the photoresistor on one side is different from the other side, and the motor is controlled to find a balance point, that is, the center of the light source. It is recommended to use a geared motor. The slower the speed, the better the effect. The 5-5.5V regulated power supply cannot be directly connected to the solar panel. When the motor is connected to the circuit board, there is no difference between the positive and negative poles. During the test, if the direction of the motor and the light source are opposite, the positions of the motor leads are opposite.
