It measures light intensity (lux), colour in CIE XY and LUV coordinates, and correlated colour temperature (CCT).\n\nThis mini breakout (0.5\" × 1\") includes two Qwiic connectors for solderless I2C daisy-chaining, plus 0.1\"-spaced header pins for breadboard use. An Arduino library is available for easy integration.\n\nKey Features\n\n\nOPT4048DTSR Sensor – Four-channel tristimulus colour sensing with close CIE 1931 spectra matching and excellent IR rejection\n\nWide Dynamic Range – 26 bits effective range from 2.15 mlux to 144 klux\n\nConfigurable Conversion Times – 12 options from 600 µs to 800 ms per channel for speed vs precision trade-off\n\nQwiic I2C Interface – Two horizontal Qwiic connectors for solderless hookup\n\nSelectable I2C Address – 0x44 (default), 0x45, or 0x46\n\nLow Power – 24 µA operating current, 2 µA standby\n\nHardware Interrupt – External pin for synchronised triggers and interrupts\n\nMini Form Factor – 0.5\" × 1\" with 0.1\"-spaced breakout pins\n\n\nSpecifications\n\n\nSensor – Texas Instruments OPT4048DTSR\n\nSupply Voltage – 1.71–3.6V\n\nInterface – I2C (Qwiic)\n\nChannels – 3× CIE tristimulus (XYZ) + 1× wide-band clear\n\nOperating Temperature – –40°C to +85°C\n\n\nIdeal For\n\nDisplay brightness and colour temperature adjustment\nCamera colour temperature correction\nTrue colour object recognition\nAmbient light measurement\nMedical and scientific colour sensing applications\n\n\nResources\n\nHookup Guide\nOPT4048 Datasheet\nArduino Library (GitHub)\nHardware Repository (GitHub)\nSchematic\nEagle Files\n","vendor":"SparkFun","product_type":"","in_stock":true,"options":[],"variants":[{"id":1327,"title":"Default Title","sku":"SF-SEN-22639","price":23.67,"on_sale":false,"in_stock":true,"available_quantity":10,"option1":"Default Title"}]}
