## Description

The Gravity Analogue Grayscale Sensor measures reflected light intensity, outputting an analogue value that ranges from black (low) to white (high). 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. Common 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. Key Features Grayscale Detection – Measures reflected light from black to white surfaces Onboard LED – Integrated white LED illuminates the target surface Analogue Output – Continuous voltage output proportional to reflected light Gravity Interface – 3-pin analogue connector for plug-and-play use 3.3–5 V Compatible – Works with both 3.3 V and 5 V logic boards Immersion Gold PCB – Durable, corrosion-resistant surface finish Specifications Supply Voltage – 3.3–5 V Interface – Analogue Dimensions – 22 × 30 mm Package Contents 1× Analogue Grayscale Sensor V2 1× Analogue cable Ideal For Line-following robots Automatic lighting control Surface brightness detection Simple optical communication experiments Resources DFRobot Wiki – Documentation & Tutorials Schematic (PDF)
