It outputs a digital signal to your microcontroller, making it ideal for line-following robots, smart car builds, and proximity-sensing automation projects. The detection distance is adjustable from 2 cm to 30 cm via the onboard potentiometer.\u003c\/p\u003e\n\u003ch4\u003eQ: How do I adjust the detection distance on this sensor module?\u003c\/h4\u003e\n\u003cp\u003eA: The detection distance is easily adjusted using the onboard potentiometer. Turning the potentiometer clockwise increases the detection range (up to 30 cm), while turning it counter-clockwise decreases the range (down to 2 cm). This makes it simple to calibrate for your specific project environment without any additional components.\u003c\/p\u003e\n\u003ch4\u003eQ: Is this infrared sensor module compatible with Arduino and Raspberry Pi?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! This module is fully compatible with Arduino, Raspberry Pi, STM32, and most other popular microcontroller and single-board computer platforms. It operates on 3.3V–5V DC and outputs a clean digital HIGH\/LOW signal, so it integrates seamlessly into your existing project wiring with minimal setup.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
