Lux measurement system design

This study is carried out to design a lux measurement system. The lux measurement system is a design to measure brightness of street light in lux. Brightness is an attribute of visual perception. It is a source appears to be radiating or reflecting light. In other words, brightness is the perception elicited by the luminance of a visual target. This is a subjective attribute or property of an object being observed. It can be measured while in moving situation. In this study, the lux measurement system was designed using a voltage divider circuit. By connecting light dependent resistor (LDR) to another resistor in series, it became a voltage divider where the voltage drop across it acts as a function of the light intensity. A voltage divider is useful in determining the voltage drop across the resistance within a series circuit. This Lux Measurement System Design has memory to store the measured values and software to analyze readings.
