Photo Reflective Sensor Module CNY70

Description

Photo Reflective Sensor Module CNY70 The Photo Reflective Sensor Module CNY70 combines a GaAs infrared emitter and a silicon planar phototransistor with an onboard LM393 comparator. When a surface is placed within 0–5 mm, IR light reflects back to the detector, triggering a logical LOW output (active-low), and illuminating an onboard LED during reflection. Designed for 3.3–5 V operation, the module features two Ø 3.5 mm mounting holes and is fully compatible with Arduino and other microcontroller platforms. Its compact dimensions, 38 × 17 × 17 mm, make it ideal for precise proximity detection, line sensing, or object detection tasks. Features Utilizes wide-voltage LM393 comparator for robust threshold control. Voltage-compatible with 3.3–5 V systems. Active-low output (LOW = object detected, LED on). 10 mA max output sink current, suitable for microcontroller GPIO. Operating detection range: 0–5 mm. Two Ø 3.5 mm mounting holes for secure installation. Breadboard-friendly and compatible with Arduino platforms. Compact 38 × 17 × 17 mm PCB size. Specifications Parameter Value Operating Voltage 3.3 V–5 V DC Detection Range 0–5 mm Output Type Active-low digital Max Sink Current 10 mA Mounting Holes 2 × Ø 3.5 mm LED Indicator Yes (active-low) Module Size 38mm × 17mm × 17 mm Applications Short-range proximity sensing and object detection.
