THE OPTICAL MEASUREMENT SUSCEPTIBILITY OF THE PHOTODIODE AND LDR LIGHT SENSORS

Abstract

Electrical parameters such as current, voltage and resistance are produced by the light-sensitive sensor elements depending on the light. Therefore, optically sensitive sensors are widely used in light measurement and light control systems. LDR (A Light Dependent Resistor) and Photodiode, which are widely used in light detection systems, have been discussed in the study, they have been exposed to different lighting values in an indoor environment. Their electrical reaction values have been measured and susceptibility analysis has been conducted. In the light of the findings obtained, it has been seen that with 9.44 standard deviation rate photodiode has shown more light sensitivity than LDR.
