You can use the ESP32 microcontroller to create some amazing and useful smart home projects.

Smart home is a home that can remotely control electrical appliances and equipment through any mobile phone or computer with Internet connection. It is usually based on a wirelessly connected device created using a microcontroller, such as an Arduino or ESP32 board.

The ESP32 microcontroller has onboard Wi-Fi and Bluetooth support, making it ideal for manufacturers and electronics enthusiasts who want to build smart home projects. Let's take a look at some of the best smart home projects built with ESP32.

This project is built using Espressif ESP32S board for monitoring the aquarium. Specifically, it allows users to schedule automatic fish feeding time or manually feed fish by touching a button in the Android app. The user can even specify the amount of food to be fed. It also has a controllable lighting system that can be customized using an RGB palette.

In addition, it also has a night mode, which can turn on the white LED light according to the current light level. With the waterproof DS18B20 temperature sensor, it can also measure the water temperature of the aquarium. The oxygen pump can also be controlled by two programming modes: low and high.

To create your own smart aquarium, follow the tutorial in the Arduino Project Center linked above.

This is an intelligent security system that can detect intruders when someone breaks in. As part of the build, the manufacturer includes a PIR motion sensor and an ESP32-CAM development board for taking security shots.

Using the Telegram application, these photos can be sent to remind users. In addition, the project also integrates flame sensors and gas sensors. Therefore, in the event of a fire or gas leak, fire, gas, and smoke detection can be performed.

This project is a Telegram robot built with ESP32. Specifically, it will send a notification to your smartphone through your Telegram account when it detects movement.

Although there are many security cameras on the market, you can create a security system for a fraction of the cost. Follow the steps outlined in the random nerd tutorial to build your own ESP32 Telegram bot.

Since Amazon Alexa does not support direct integration with webcams running within your network, the manufacturer created Monocle for this purpose, which is an online gateway service.

Specifically, it allows you to view and control cameras with pan/tilt zoom function. It also allows you to control cameras that do not have a built-in cloud connection.

The example device built here uses several different microcontrollers, including the Arduino MKR1000 and Espressif ESP32S, and the Raspberry Pi zero W single board computer.

Use your voice to control up to four appliances. This project uses ESP32 and a four-channel relay module to operate four bulbs. It also includes a DHT11 temperature/humidity sensor, an infrared sensor and button switches.

It allows you to control the device using Amazon Alexa or Arduino IoT Cloud dashboard. According to the manufacturer, you don't even need an Alexa device built for this. Instead, they chose to use the free version of Arduino IoT Cloud.

This barista robot is equipped with ESP32 and Arduino Nano R3! It uses the hand pouring technique of a skilled barista to produce the kind of high-end handmade coffee you expect.

Customize its three brewing stations with various recipes through a web application and personalize each brew. Some parameters can be set, such as brewing time, rest time, how much water to use, and the mode used when pouring manually.

Use this complete smart home project to turn ceiling fans and lights on and off. According to the manufacturer, up to 16 loads can be turned on or off by using Android, iOS, Windows or other network-based devices.

Build your own complete smart home by completing the instructions on the Instructables linked above.

Use this DIY smart energy monitor made of ESP32 and Raspberry Pi and Home Assistant home automation software to check your energy usage.

Essentially, it uses sensors in the grid to measure current and voltage samples. Then use Home Assistant and Raspberry Pi to send this data to the local server. Follow the complete step-by-step tutorial on Instructables to make your own smart Arduino energy monitor.

Constructed with ESP32 and 3D printed shell, it is a smart wallet for tracking the value of your cryptocurrency or stocks!

Essentially, it reads the values ​​from the Google spreadsheet on the ESP32 and then displays them on the OLED display. There is also a built-in clock synchronized with the Internet, and a pedometer.

Build your own IoT smart wallet and track all your cryptocurrencies and stocks.

This is no ordinary doorbell: it is a smart doorbell that relies on visual alarms instead of sounds. The manufacturer created it because it is more suitable for his work settings, so he does not need to pick up the noise-reducing headphones to check if the doorbell is ringing during the video conference.

It will flash when the doorbell button is pressed, and it will also receive various visual signals based on notifications. This project is made using ESP8266 ESP-01 and ESP32-CAM and NeoPixel LED ring.

In this article, we learned about smart home projects made with ESP32 microcontrollers. Many of these projects also contain other components, such as Arduino development boards. However, they all maintain a relatively low cost, so they can be used by a wider community.

If you haven't read it yet, please be sure to check ESP 32's Espressif IoT Development Framework document.

Wireless-Tag's WT32-ETH01 brings all the advantages of ESP32 through the added Ethernet port.
