Its unique right-angle orientation senses light coming parallel to the PCB surface rather than perpendicular — ideal for edge-lit enclosures and side-mounted installations.\n\nThe VEML7700 provides 16-bit dynamic range for ambient light detection from 0 lux to approximately 120 klux, with resolution down to 0.0036 lx/ct. Gain and integration times are software-adjustable for different lighting conditions.\n\nKey Features\n\n\nRight-Angle Sensing – Detects light parallel to the PCB surface, unlike most top-facing sensors\n\nCalibrated Lux Output – Returns SI lux values for consistent, meaningful readings across sensors\n\n16-Bit Dynamic Range – 0 to ~120,000 lux with 0.0036 lx/ct resolution\n\nI2C Interface – Simple two-wire connection with STEMMA QT / Qwiic connectors for solderless hookup\n\nSoftware-Adjustable – Configurable gain and integration time\n\nWide Compatibility – Arduino and CircuitPython libraries available; works with microcontrollers and SBCs including Raspberry Pi\n\n\nIdeal For\n\nAmbient light measurement in enclosures with side-mounted sensors\nAutomatic display brightness adjustment\nEnvironmental monitoring and data logging\nSmart lighting and energy management systems\n\n\nPackage Contents\n\n1× Adafruit Right Angle VEML7700 Lux Sensor Breakout\n\n\n\nNote: STEMMA QT / Qwiic cable is not included. Use a compatible JST SH cable for solderless connection, or solder directly to the header pads.\n\n\nResources\n\nSTEMMA QT Overview\nArduino Library (GitHub)\nCircuitPython Library (GitHub)\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":2413,"title":"Default Title","sku":"AF-5378","price":10.05,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":2,"option1":"Default Title"}]}
