How To Use IR Sensor With Raspberry Pi Pico Using Micropython

In this guide, we will be showing you how to use an IR sensor with your Raspberry Pi Pico using MicroPython. We will also be providing you with a code example to help you get started. We will also learn how to interface an IR sensor with Raspberry Pi Pico

Required Material

IR Infrared Obstacle Avoidance Sensor

IR sensor is used to detect the presence of an object by emitting and detecting infrared radiation.is a very popular sensor which is used in many applications like remote control, proximity sensor, line following robots security systems, etc. The working of an IR sensor is very simple. It consists of an IR transmitter and an IR receiver.

The IR transmitter emits infrared radiation which is detected by the IR receiver. When an object is placed in front of the IR sensor, the infrared radiation is reflected back to the receiver. This change in the intensity of the received infrared radiation is used to determine the presence of an object.
