{"title":"Ambient Light Sensor(0-200klx)","handle":"ambient-light-sensor-0-200klx","url":"/products/ambient-light-sensor-0-200klx","description":"A high-precision ambient light sensor housed in a transparent semisphere case for optimal light-gathering performance. With a wide 0–200 klx detection range and I2C communication, this sensor is ideal for applications requiring accurate ambient light measurement across a broad range of conditions.\n\nThe on-chip photodiode features a spectral response optimised to mimic the human eye's perception of ambient light, with built-in IR and UV blocking. An adaptive gain block automatically selects the optimal lux range to maximise accuracy at any light level.\n\nKey Features\n\n\nWide Detection Range – 0 to 200 klx covers everything from moonlit nights to direct sunlight\n\nHuman Eye Response – Spectral response matched to human visual perception\n\nIR & UV Blocking – Filters out infrared and ultraviolet for accurate visible light measurement\n\nAdaptive Gain – Automatically optimises counts/lux for the current light level\n\nI2C Interface – Simple digital communication with microcontrollers\n\nTransparent Semisphere Housing – Enhanced light collection from all angles\n\n\nSpecifications\n\n\nSupply Voltage – 2.7V to 6V\n\nOperating Current – 0.7mA\n\nDetection Range – 0 to 200 klx\n\nResolution – 0.054 lx\n\nInterface – I2C\n\nOperating Temperature – -40°C to +85°C\n\nDimensions – Inner diameter 22mm, outer diameter 26mm, shell diameter 28.5mm, semisphere height 18mm\n\n\nLuminance Reference\n\n\nEvening – 0.001–0.02 lx\n\nMoonlit night – 0.02–0.3 lx\n\nCloudy indoor – 5–50 lx\n\nCloudy outdoor – 50–500 lx\n\nSunny indoor – 100–1,000 lx\n\nReading light – 50–60 lx\n\nVideo standard – 1,400 lx\n\n\nIdeal For\n\nSmart lighting and display brightness control\nVehicle automatic headlight systems\nGreenhouse and agricultural light monitoring\nEnvironmental data logging\n\n\nPackage Contents\n\n1× Ambient Light Sensor (0–200 klx)\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":3492,"title":"Default Title","sku":"DF-SEN0390","price":11.94,"on_sale":false,"in_stock":true,"available_quantity":245,"option1":"Default Title"}]}
