Abstract :
Light signals is turned into electrical signals by the photoelectric sensor. The amplifier circuit amplify weak current signal to a certain range of voltage signals[1], using high precision 16-bit AD converter MAX1134 into digital signal. MCU control segment LCD displaying the data, and finally through the exact calibration display the values of illumination. Experiments show that the circuit design has steady performance and better reliability, and visual sensation character meet the requirements of CIE.
