🔧 Key Features:
16 Reflective IR Sensors (QRE113GR)
Detects surface reflectivity with high sensitivity, ideal for tracking lines, edges, and proximity detection.
Integrated 74HC4067 Multiplexer
Seamlessly reads all 16 channels using just one analog pin and four digital select lines, simplifying wiring and code complexity.
Analog Output
Each sensor provides analog voltage output, allowing fine-grained surface differentiation (ideal for black vs white detection).
Compact & Modular Design
Sleek PCB layout ready to mount directly on robots or automation platforms. Easily stackable or extendable for larger setups.
Low Power Consumption
Optimized for both 3.3V and 5V systems, making it compatible with Arduino, ESP32, Raspberry Pi, and more.
