Present article deals with selection and study of microcontroller required for the construction of modern sun photometer. Construction of photometer essentially requires parts like ADC, floating point processor, electrically erasable memory and input /output (IO) ports. Development of microelectronics is now a constant process and the new devices like Bluetooth and Wi-Fi would make sun photometer portable so that it can be placed at remote locations. In recent years, there is tremendous development in the microcontroller capability particularly in the field of data conversion, digital communication and arithmetic processing. Use of such microcontroller improves the performance of photometer particularly the parameters like sensitivity, accuracy and precision are improved. This article is helpful to the instrumentation engineers and researchers working in the field of astronomy and astrophysics.
