Embodiment Construction

[0032] Such as figure 1 As shown, an automatic detection device for the sun direction detection device, including regular polygon base 1, light intensity sensor 2 (model: GY-30), embedded control chip 3 (model: cortex-M3STM32), Bluetooth communication chip 4 (model: Bluetooth module HC-06), photovoltaic power supply module 5, LCD display (model: LCD12864) 6, geomagnetic sensor 7 (model: MAG3110).

[0033] (1) When the photovoltaic module 5 receives sufficient sunlight intensity, it will provide the entire detection system with the power required for work. The system starts working. Such an invention not only saves energy, but also ensures the working efficiency of the system, and will not waste electricity in an environment that does not need to be detected.

[0034] (2) After the system starts to work, the embedded control chip 3 communicates through the IIC bus, reads the light intensity sensor 2 on each surface of the base 1, and judges the sun through the relationship be...
