Abstract A solar radiometer system based on MSP430F1611 is designed.In order to measure global horizontal irradiance,diffuse horizontal irradiance and direct normal irradiance,the motor drives the shading band that blocks the photodiode intermittently through the MCU control.The 24 bit high-precision A/D chip ADS1255 collects the data to guarantee its accuracy.The system ensures the timing of data through the clock chip,outputs minute data with RS232 and stores the effective historical data into the FLASH chip.The features of the system are stable operation,reliable practice and high performance price ratio.
