The controller is a dual-axis sunlight tracking controller that uses high-precision inner and outer ring-hole sensors to detect the direction of the sunlight. The sensor signal is analyzed and judged through the microcontroller circuit on the controller to execute the entire process of tracking the sunlight. The corresponding motor of the platform is controlled through the relay assembly on the circuit board. It also has functions such as windward leveling (optional wind speed sensor required), cloudy or cloudy day reset, etc. At night, use the English LCD screen to indicate the corresponding parameters, and use the buttons on the controller or the buttons on the infrared controller (optional remote control required) to set the parameters. The platform requirement corresponding to this controller is a dual-degree-of-freedom platform. The platform motor is a DC brush motor, the motor voltage is 12V or 24V, and the single motor current must be less than 15A (the default configuration is a 10A fuse for each axis). There should be limit switches in all four directions of the platform.
