High Precise Self-Adaptive Digital Illuminometer-Based CPLD

Conference paper
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 138)


The paper designs a kind of self-adaptive digital illuminometer of high accuracy. The meter consists of silicon photocell, current to voltage converter, auto gain amplifier with complex programmable logical device, analog value to digital value converter, liquid crystal display. The illuminometer has many advantages of wide measurement range, short response time, high photoelectric conversion efficiency, high resolution, and high portability, so it is very useful in many fields.
