## Description

The Adafruit BH1750 Light Sensor is a 16-bit ambient light sensor from Rohm that provides measurements directly in lux — the SI unit for illuminance. This makes it easy to compare readings against reference values or other sensors without manual calibration or conversion. Packaged on a STEMMA QT breakout with a voltage regulator and level shifting, the BH1750 works with both 3.3V and 5V devices. STEMMA QT / Qwiic connectors provide solderless I2C wiring, and all pins are also broken out to a standard 0.1" header for breadboard use. Key Features 16-bit Lux Output – Direct digital readings in lux from 0 to 65,535+ lux (up to ~100,000 lux with advanced calibration) I2C Interface – Simple two-wire communication with selectable address 3.3V and 5V Compatible – Onboard voltage regulator and level shifting STEMMA QT / Qwiic Connectors – Solderless I2C connection, chainable with other devices Standard Header Breakout – 0.1" pitch pins for breadboard use Wide Platform Support – Arduino, CircuitPython, Python (Raspberry Pi), and MCP2221 compatible Ideal For Automatic display brightness adjustment Light-following robots and solar trackers Day/night detection for automation Environmental monitoring and data logging Package Contents 1× Adafruit BH1750 Light Sensor Breakout (STEMMA QT) Note: STEMMA QT cable not included.
