Abstract: Within the past few years a number of different designs of photoelectric calorimeters have been described in the literature. This paper addresses the absorbance measurement of visible light through different sample solutions at different range of wavelengths by using different colour filter and the results have been compared with the absorbance values obtained by a digital colorimeter. The Absorbance measurement has then been shown on an 16×2 LCD display by use of a PIC16F877a microcontroller.
Keywords: LED, LDR, colorimeter, Absorbance, Filter, wavelength, LCD, Microcontroller.
