This makes it easy to compare readings against reference values or other sensors without manual calibration or conversion.\n\nPackaged 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.\n\nKey Features\n\n\n16-bit Lux Output – Direct digital readings in lux from 0 to 65,535+ lux (up to ~100,000 lux with advanced calibration)\n\nI2C Interface – Simple two-wire communication with selectable address\n\n3.3V and 5V Compatible – Onboard voltage regulator and level shifting\n\nSTEMMA QT / Qwiic Connectors – Solderless I2C connection, chainable with other devices\n\nStandard Header Breakout – 0.1\" pitch pins for breadboard use\n\nWide Platform Support – Arduino, CircuitPython, Python (Raspberry Pi), and MCP2221 compatible\n\n\nIdeal For\n\nAutomatic display brightness adjustment\nLight-following robots and solar trackers\nDay/night detection for automation\nEnvironmental monitoring and data logging\n\n\nPackage Contents\n\n1× Adafruit BH1750 Light Sensor Breakout (STEMMA QT)\n\n\n\nNote: STEMMA QT cable not included.\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":4101,"title":"Default Title","sku":"AF-4681","price":9.15,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":109,"option1":"Default Title"}]}
