A digital ambient light sensor module based on the BH1750FVI IC, providing light intensity readings in lux (lx) via I2C. The sensor offers a wide measurement range from 1 to 65,535 lx with ±20% accuracy, making it suitable for automatic backlight adjustment, photography lighting measurement, and environmental monitoring.

The module is .NET Gadgeteer compatible and operates on 3–5 V, with two selectable I2C slave addresses for flexible bus configuration.
