FPGA-Based High Precision Illumination Measurement System: A Prototype Development and Evaluation

Abstract

The light is a most important natural resource for human to survive .Aiming at the shortcomings of the traditional light intensity measuring instrument ,a kind of high resolution illumination measurement system based on FPGA is designed ,which consists of special BH1750 light sensors and programmable logic gate array (FPGA) . A soft core Nios II is used as controller in the instrument, and BH1750 is put into use to acquire light signal .The testing results show that the design is feasible.
