It uses high-precision inner and outer ring hole sensors to detect the direction of sunlight. Users can analyze and judge the sensor signal through the single-chip microcomputer circuit on the controller. The corresponding motor on the platform can be controlled through the relay combination on the circuit board to perform the process of tracking the sun. At the same time, you can lay it flat in case of wind (wind speed sensor needs to be purchased), and it can return to the position on cloud days or nights. English LCD screen is used to display the corresponding parameters, and the parameters can be set by the buttons on the controller or the buttons of an infrared remote control (remote control needs to be purchased). This controller corresponding platform required to be 2-axis platform, the drive motor of platform is DC brush motor, the motor voltage is 12V or 24V, and current of single motor must be less than 15A (each axis with a 10A fuse by default). Four direction of platform all should have limit switch. DC IN: 10-28V; DC OUT=DC IN; And MAX.
