1.Solar Energy Panel Automatic Tracking Sensor Module
2.Principle:Put shelter on the photo resistor.When the light shines on the shelter and forms a shadow,the photo resistor on one side forms a difference with the other side,control the motor and to find the balance point,that is the central of the light source.
3.Recommend to use reduction motor.The slower the speed is,the better it will be.4.5-5.5V regulated supply voltage,cannot directly connect the solar panel.
4.When the motor connects the board, there is no difference of positive and negative.When testing,if the motor rotates toward the opposite direction of the light source,then reverse the motor wire position
