If you're attempting to make a basic motion sensor project with an Arduino and a PIR sensor, you're on the right site. Throughout this tutorial, I'll take you through how to assemble the circuit, sensor calibration, code, and test your prototype.

Apr 6, 2024 · In this tutorial, you’ll learn how to create an Arduino PIR Sensor. PIR stands for Passive InfraRed. The PIR sensor is widely used in motion detection applications and this project will show you how to use it to control an LED. When the sensor detects motion, the LED will turn on and the event will be logged via the serial monitor.

Apr 30, 2024 · In this article, We will learn how can we make a Motion Detection System using Arduino. When the PIR Sensor will detect any motion, it will show that on the Serial Monitor and the buzzer will start.

Jun 22, 2021 · In this basic tutorial we are going to see how to interface Arduino uno with PIR motion sensor ( HC-SR501 ). So let's start !!! First of all we need to know what is motion sensor and how it works ?

Mar 10, 2025 · When paired with an Arduino, a motion sensor can be programmed to respond intelligently, creating an efficient and responsive system. This guide explains how motion sensors work, how to connect them to an Arduino, and how to write the code needed to make them function properly.

Dec 20, 2023 · In this tutorial, we will be building a simple Arduino motion sensor that makes use of a PIR sensor to be able to detect motion. This simple circuit can be extended to do some pretty cool stuff, for example, activate lights, a speaker and much more.

Aug 8, 2024 · How does the sensor work? The motion sensor has two slots, each made of a special infrared-sensitive material. When the sensor is inactive, both slits detect the same amount of IR, the ambient amount emitted from the room.

A PIR sensor lets your Arduino sense movement without contact. This tutorial covers PIR sensor basics, connecting one to an Arduino board and coding a motion detector.

Feb 4, 2023 · Connect the HC-SR501 PIR motion sensor to the Arduino according to the sensor’s documentation. Typically, the HC-SR501 PIR motion sensor has four pins: VCC, GND, OUT, and ADJ.
