ESP32 Projects

Introduction Ever wanted to measure temperature without actually touching anything? Meet the MLX90614, a cool little infrared sensor that lets you do just that! Whether you’re building a DIY thermometer, automating your home, or monitoring industrial equipment, this sensor has got you covered. We have already covered how to use …

In this tutorial, we will build a simple yet powerful data logger using the ESP32 microcontroller. The device will: Read temperature data using a sensor (e.g., DS18B20 or DHT11/22). Store the data on an SD card. Provide real-time monitoring via a web server using WebSockets.

This tutorial guides you through building a heart rate sensor project using an ESP32 and a MAX30102 breakout board. The heart rate data is dynamically displayed on a web page hosted locally by the ESP32, enabling real-time updates without the need to refresh the page. Devices connected to the same …

In this tutorial, we will build a web-based fire alarm system using an ESP32 microcontroller, a flame sensor, a smoke sensor, and Arduino Cloud. This project will provide real-time alerts and allow you to monitor fire-related events remotely via a web interface.

A solenoid lock is an electric actuator that converts electrical signals to motion. It is commonly found in electronically controlled doors and drawers. Using the solenoid lock with a microcontroller is easy and, if you’re a beginner, this project is just for you.

When working with IoT, it’s often necessary to track a device’s location for monitoring. Global Positioning Service (GPS) remains the number 1 option for large-area tracking. This project will show you how you can use a GPS with an ESP32 and have the location plotted on Google Maps.

This ESP32-powered project allows you to write messages to a MAX7219 LED matrix display using your smartphone. Scaled up, this can be used as a WiFi message board for schools or signages for businesses.

For this article, I will show you how to use an ESP32 microcontroller as a magnetometer – a device that measures the direction and strength of a nearby magnet. In the absence of a nearby magnet, the device detects the Earth’s magnetic field. Hence, a compass is a type of …

The ESP32 has become one of my favorite microcontrollers as it’s compact, relatively cheap, and contains 125% higher memory than an Arduino UNO.
