Mar 16, 2022 · In this Arduino IR sensor module tutorial we are explaining how to connect IR sensor module with Arduino Uno and write the code to get the IR motion sensor working.

Feb 2, 2025 · In this guide, we will go through basics of connecting the IR Sensor Module to an Arduino UNO board. We will also discuss writing the code necessary for the Arduino to interpret the signals from the IR sensor.

In this article we will see how to setup a PIR sensor on the Arduino, and use the sensor’s input to control a 5V relay. Watch the video for this tutorial here:

How to Use IR Infrared Sensor With Arduino: Welcome back to my blog. We described the PIR(Motion) sensor in the previous post. Today we are going to talk about the IR sensor modules in this post. This sensor is the most important for making robots. I promise to present those projects in the n…

Learn about HC-SR501 Passive Infrared PIR Motion Detector module. This tutorial includes working, Pinout, Wiring/Schematic, Arduino Code & standalone use.

An IR sensor is an electronic instrument used to sense certain characteristics of its surroundings by either emitting and/or detecting Infrared radiation. Infrared sensors can also measure heat emitted by an object and detect motion.

Feb 2, 2025 · This guide focuses on interfacing of the HC-SR501 PIR (Passive Infrared) Motion Sensor with an Arduino UNO Board. The HC-SR501 sensor is designed to detect motion through infrared signals emitted by living beings, making it ideal for applications like security systems, automated lighting, and motion-activated devices.

Now we have a clear understanding of how an IR sensor works, we can interface IR sensor to Arduino as shown below. In the above wiring diagram, Arduino Uno is connected with the IR Proximity Sensor. The VCC pin of sensor is connected to the 5V pin on the Arduino.
