Aug 3, 2018 · This tutorial shows how to detect motion with the ESP32 using a PIR motion sensor. In this example, when motion is detected (an interrupt is triggered), the ESP32 starts a timer and turns an LED on for a predefined number of seconds.

Feb 10, 2022 · Today, we are going to interface an external embedded sensor(i.e. PIR Sensor) with the ESP32 Microcontroller board. At the start, we will discuss the basics of a PIR Sensor(HC-SR501) i.e. its pinout and working.

In this guide, we will learn how to Interface the PIR Motion sensor with ESP32 and detect the motion of living objects. here we are displaying the result on a serial monitor using ESP32 and Arduino IDE.

Nov 29, 2022 · In this article, we interface HC-SR501 PIR sensor module with ESP32. HC-SR501 PIR sensor module allows you to detect when a person or animal moves in or out of the range of your sensor.

Dec 12, 2023 · Interrupts are a key feature in microcontrollers, allowing the ESP32 to react instantly to changes detected by the PIR sensor. Instead of continuously polling the sensor’s status, which is resource-intensive, the ESP32 can perform other tasks and only respond when the sensor detects motion.

Sep 5, 2021 · In this comprehensive guide, we learned how to effectively integrate a PIR (Passive Infrared) motion sensor with the versatile ESP32 microcontroller. This project exemplified the importance of interrupts and timers for handling real-time events, such as motion detection.

Feb 16, 2024 · In this tutorial, we will learn how to interface a Passive Infrared (PIR) sensor with the ESP32 microcontroller. PIR sensors are widely used for motion detection and can be incorporated into various IoT projects for home automation, security systems, and more.

Jan 13, 2025 · Discover how to integrate and use PIR sensors with the ESP32 for motion detection. This guide covers wiring, code examples, practical applications, and troubleshooting tips for beginners and advanced users alike.

A PIR sensor allows detecting motion of a body. The PIR indicates Pyroelectric Infrared or it also referred to as Passive Infrared Sensor. The working principle of the PIR sensor is the detection of infrared energy emitted by the moving body. The operation of the PIR sensor is very simple.

In this project demonstration, we will show you how to convert an existing project into a smart project using the ESP32 development board. The ESP-based EzloPi device provides the capability to convert your hardware (projects or devices/sensors) into IoT-capable devices.
