Description
Description
The BH1750 is a digital ambient light intensity sensor module designed for accurate illumination measurement in lux using the I2C interface. It provides direct digital light readings without the need for analog-to-digital conversion, ensuring stable and reliable results. The module integrates a 3.3 V voltage regulator, allowing safe operation with both 3.3 V and 5 V microcontrollers. On-board I2C pull-up resistors simplify hardware integration and reduce external components. This sensor is suitable for Arduino-based projects, smart lighting systems, and environmental monitoring applications.
