It uses a photocell paired with an integrated white LED to illuminate the surface being measured, making it effective for detecting surface brightness and colour differences.\n\nCommon applications include line-following robots, automatic lighting systems that respond to ambient light levels, and simple optical data transmission. The Gravity interface makes it easy to connect to Arduino and compatible boards without soldering.\n\nKey Features\n\n\nGrayscale Detection – Measures reflected light from black to white surfaces\n\nOnboard LED – Integrated white LED illuminates the target surface\n\nAnalogue Output – Continuous voltage output proportional to reflected light\n\nGravity Interface – 3-pin analogue connector for plug-and-play use\n\n3.3–5 V Compatible – Works with both 3.3 V and 5 V logic boards\n\nImmersion Gold PCB – Durable, corrosion-resistant surface finish\n\n\nSpecifications\n\n\nSupply Voltage – 3.3–5 V\n\nInterface – Analogue\n\nDimensions – 22 × 30 mm\n\n\nPackage Contents\n\n1× Analogue Grayscale Sensor V2\n1× Analogue cable\n\n\nIdeal For\n\nLine-following robots\nAutomatic lighting control\nSurface brightness detection\nSimple optical communication experiments\n\n\nResources\n\nDFRobot Wiki – Documentation & Tutorials\nSchematic (PDF)\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":11234,"title":"Default Title","sku":"DF-DFR0022","price":4.38,"on_sale":false,"in_stock":true,"available_quantity":372,"option1":"Default Title"}]}
