{"title":"MAX44009 Wide-Range Lux Light Sensor Breakout","handle":"adafruit-max44009-wide-range-lux-light-sensor-188-000-lux-max","url":"/products/adafruit-max44009-wide-range-lux-light-sensor-188-000-lux-max","description":"Measure ambient light in real lux with a sensor that handles everything from very dim conditions to bright outdoor sunlight. This breakout is built around the MAX44009, an easy-to-use ambient light sensor that automatically ranges across a very wide span, so you can get smooth readings without constantly tweaking gain or integration settings.Unlike simpler light sensors that only return an arbitrary brighter/darker value, this board calculates lux directly using the SI unit for light. That makes readings easier to compare between different projects and between multiple sensors. If you want more control, the MAX44009 also supports software-adjustable integration times, or you can leave it to auto-range for convenient operation.The breakout uses standard I2C for communication and includes both a 3.3V regulator and logic level shifting, making it suitable for either 3.3V or 5V microcontroller setups. Adafruit also includes SparkFun qwiic-compatible STEMMA QT connectors for quick solderless connections. Library support is available for Arduino (C/C++) and CircuitPython (Python 3), so it fits neatly into projects with microcontrollers or single-board computers such as Raspberry Pi.Specifications:Sensor: MAX44009Dynamic range: 22-bitAmbient light detection range: 0.045 lux to 188,000 luxMaximum light level: about 188 kluxResolution: 0.045 per least-significant-bitIntegration time: software-adjustableAuto-ranging: supportedInterface: I2COnboard regulator: 3.3V regulatorLogic compatibility: logic level shifter for 3.3V or 5V power/logic microcontrollersConnectors: SparkFun qwiic compatible STEMMA QT connectors for the I2C busA handy choice for datalogging, smart lighting, display brightness sensing, environmental monitoring and daylight-aware projects. Please note that a QT cable is not included.","vendor":"Adafruit","product_type":"Light Sensor","in_stock":false,"options":[],"variants":[{"id":15528,"title":"Default Title","sku":"AF-6498","mpn":"ADA6498","price":29.84,"on_sale":false,"in_stock":false,"available_quantity":0}]}
