The Top 10 ESP32 Projects for Smart Homes

With an ESP32 microcontroller, you can create some incredible and practical smart home projects.

A smart home is one where appliances and devices may be operated remotely from any phone or computer with an internet connection. Typically, it is built around wirelessly linked devices that are created using microcontrollers, such as an Arduino or an ESP32 board.

Making it perfect for makers and electronics enthusiasts looking to develop their smart home projects, the ESP32 microcontroller offers built-in Wi-Fi and Bluetooth capabilities. Let's look at some of the top ESP32-based smart home projects.

1. Smart Aquarium

This project uses an Espressif ESP32S board to monitor the aquarium. At the press of a button on an Android app, users may schedule when the fish will be fed automatically or manually. Users may even specify the amount of food that needs to be fed. Moreover, it offers a customizable RGB lighting system that can be controlled.

Additionally, it includes a night mode in which white LED lights are turned on depending on the current light level. It can also detect the warmth of the aquarium water using a waterproof DS18B20 temperature sensor. Two programmed modes—low and high—can likewise be used to operate an oxygen pump.

Follow the tutorial in the Arduino Project Hub to build your own smart aquarium.

2. Home Security System Using ESP32-CAM and Telegram App

In the event of a break-in, this smart security system can identify intruders. The maker has added a PIR motion sensor and an ESP32-CAM development board to take part in security footage.

These photos may be sent to the user as an alert using the Telegram app. The project also includes a flame sensor and a gas sensor. In the case of a fire or gas leak, there is smoke, gas, and fire detection.

This project is an ESP32-based Telegram bot. Particularly, anytime it senses motion, it sends notifications to your smartphone through a Telegram account.

Even if there are many security cameras on the market, you could build a security system using them for a fraction of the price. Follow the instructions outlined in Random Nerd Tutorials to create your own ESP32 Telegram bot.

4. Monocle: View & Control IP Cameras

Since Amazon Alexa does not support direct integration with web cameras within your network, the maker created Monocle, an online gateway service running for this purpose.

It specifically lets you view and control your cameras with pan-tilt-zoom capabilities. It also allows you to control cameras without an internet connection.

The example device built here uses a variety of microcontrollers, including the Arduino MKR1000 and Espressif ESP32S, as well as a Raspberry Pi Zero W single-board computer.

5. Alexa Voice Control Smart Home

You can use the sound of your voice to control up to four appliances. Using an ESP32 and a four-channel relay module, this project operates four light bulbs. A DHT11 temperature/humidity sensor, an IR sensor, and push-button controls are also included.

It lets you control devices using Amazon Alexa or the Arduino IoT Cloud dashboard. The maker claims that this construction does not even need an Alexa device. Instead, they've opted for a free version of Arduino IoT Cloud.

9. IoT Smart Wallet


It's a smart wallet for tracking the value of your cryptocurrencies or stocks, built using an ESP32 and 3D-printed enclosure!

It just pulls values from a Google spreadsheet onto the ESP32 and displays them on an OLED display. There is also a built-in clock that is synchronized with the internet, as well as a step pedometer.

Create your own IoT smart wallet to manage all of your cryptocurrencies and assets.

10. Door Bell Set for Home Assistant

This is not your typical doorbell; it is a smart doorbell that uses a visual alert in place of sound. To avoid having to remove his noise-canceling headphones during video conferences to check whether the doorbell is ringing, the maker created them since it is more suited to his work setting.

When the doorbell button is pushed, it blinks and receives different visual signals depending on the notice. The project is made using an ESP8266 ESP-01, an ESP32-CAM, and a Neopixel LED ring.

Which Smart Home Project Is Right for You?
