Built around the Vishay VEML7700 IC, it features a 16-bit ADC, a high-sensitivity photodiode, and a low-noise amplifier — delivering precise light measurements without the need for manual voltage-to-lux calculations.\n\nWith a measurement range of 0–120,000 lx and a resolution of 0.0036 lx/ct, this sensor significantly outperforms basic photoresistors and the older BH1750 (limited to 65,000 lx). The Gravity I²C connector makes wiring straightforward with compatible DFRobot controllers and Arduino boards.\n\nKey Features\n\n\nDirect Lux Output – Digital readings in lux via I²C, no manual conversion required\n\nHigh Precision – 0.0036 lx/ct resolution for accurate low-light measurement\n\nWide Range – 0–120,000 lx (up to 167,000 lx in extended mode)\n\n16-Bit ADC – High-resolution digitisation of light levels\n\nLow Power Consumption – Suitable for battery-powered and IoT applications\n\nGravity I²C Interface – Plug-and-play connection to compatible controllers\n\n\nSpecifications\n\n\nSensor IC – Vishay VEML7700\n\nInterface – I²C (Gravity connector)\n\nMeasurement Range – 0–120,000 lx (extended to 167,000 lx)\n\nResolution – 0.0036 lx/ct\n\nADC – 16-bit\n\nOperating Voltage – 3.3–5 V\n\n\nIdeal For\n\nAmbient light monitoring and data logging\nAutomatic brightness adjustment in displays or lighting\nWeather stations and environmental sensing\n\n\nPackage Contents\n\n1× Gravity VEML7700 Ambient Light Sensor Module\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":9480,"title":"Default Title","sku":"DF-SEN0228","price":16.77,"on_sale":false,"in_stock":true,"available_quantity":221,"option1":"Default Title"}]}
