P2Y0A41SK0F 4-30cm Infrared Proximity Sensor (IR Analog Distance Sensor)

The P2Y0A41SK0F Infrared Proximity Sensor is a compact analog distance sensor designed for accurate short-range object detection. It uses infrared triangulation technology to measure the distance of nearby objects and provides an analog voltage output proportional to the measured distance. With a sensing range of 4cm to 30cm, the sensor delivers stable and reliable performance for embedded systems requiring precise close-range distance measurement.

This sensor is widely used in robotics, obstacle avoidance systems, autonomous vehicles, industrial automation, object detection, and smart electronic projects. Its analog output can be directly connected to the ADC input of microcontrollers such as Arduino, ESP32, STM32, and Raspberry Pi (with an external ADC).
