Adafruit BH1750 Light Sensor - STEMMA QT / Qwiic

The BH1750 Ambient Light Sensor is a compact and capable device from Rohm that measures light intensity with impressive accuracy. This sensor provides 16-bit light measurements in lux, covering a range from 0 to over 65,000 lux, with possibilities to measure up to 100,000 lux through calibration.

Designed for microcontroller projects, the sensor is integrated onto a PCB with a voltage regulator and level shifting circuitry, making it compatible with 3.3V and 5V devices like Raspberry Pi, Arduino, and more. The standard 0.1" header and SparkFun Qwiic compatible STEMMA QT connectors ensure easy connectivity without soldering.

Whether adjusting display brightness or navigating robots towards optimal lighting, the BH1750 is an ideal choice. The accompanying software supports CircuitPython devices and computers such as Raspberry Pi, with additional Arduino libraries and learning resources available to guide users through setup and application.
