SHARP GP2Y0A41SKOF Analog IR Distance Sensor for Arduino (4-30cm)

The SHARP GP2Y0A41SKOF is a compact infrared distance sensor designed for reliable short-range proximity measurement between 4 cm and 30 cm. Providing a linear analog voltage output, it is an ideal sensing component for students, educators, and hobbyists building autonomous mobile robots and interactive electronics projects.

Precise short-range detection

The sensor delivers accurate distance measurements across a range of 4 cm to 30 cm (1.57 to 11.81 inches). It produces an analog output voltage ranging from 0.3 V to 3.1 V, enabling straightforward distance calculations on analog-capable microcontrollers.

Simple microcontroller integration

Operating on a standard 4.5 V to 5.5 V power supply with a 33 mA operating current, the unit connects directly to development boards such as Arduino and Raspberry Pi. The built-in JST connector allows for quick, plug-and-play wiring.

Compact physical dimensions

With a footprint of 40 x 20 x 13.5 mm (1.57 x 0.79 x 0.53 inches), this lightweight module fits easily into space-constrained assemblies. Its compact design simplifies mounting on small robot chassis and smart hardware enclosures.

Robotics and automation uses

This sensor is widely used in robotic navigation for obstacle avoidance, cliff detection, and edge sensing. It is also suitable for personal cleaning robots, sanitary automation equipment, and NFC-based key reminder devices.

Included package contents

Each package contains one authentic SHARP GP2Y0A41SKOF analog IR distance sensor along with one dedicated sensor interface cable.
