In this project, we will make a Arduino based LUX Meter Using BH1750 and OLED Gauge Display. Sometime we need to measure the exposure of light but a lux meter costs is high. Here to learn low cost and accurate ambient lighting sensor BH1750 interface with arduino with OLED Gauge display and enjoyed it. In this Project Push Button added for HOLD the Lux meter display value if pressed and Reading value displayed again push button pressed.
