This paper introduces the light intensity sensor developed by the author using the principle of photoelectric conversion of photosensitive elements. Several factors that affect the performance of light intensity sensor are analyzed. Several calibration methods are compared and a method is selected to calibrate the sensor. The measured curve of the light emission of diesel engine during several operating conditions is given in this paper.
