Introduction
Did you know that 75% of developers struggle to integrate AI into their IoT projects, and it's not due to the complexity of the tech, but rather the lack of practical guidance? Last week, I spent hours trying to get started with esp32-ai, only to realize that I was overcomplicating things. In this tutorial, you will build a simple AI-powered IoT project using esp32-ai that you can use today. Mastering esp32-ai is crucial in 2026, as it enables developers to create intelligent IoT devices that can interact with their environment. To get started, you will need:
- Basic knowledge of Python programming
- An esp32 board with AI capabilities
- A computer with Python installed
- A code editor or IDE

Step 1 — Setting up the esp32-ai environment
Setting up the environment is crucial, as it determines the success of the project. To set up the environment, you will need to install the esp32 board drivers and configure the AI framework.
import os
import sys
# Install the esp32 board drivers
os.system("pip install esptool")
# Configure the AI framework
os.system("pip install tensorflow")
Expected output:
Collecting esptool
Downloading esptool-3.3.1-py3-none-any.whl (113 kB)
Collecting tensorflow
Downloading tensorflow-2.10.0-cp39-cp39-win_amd64.whl (457 MB)
Step 2 — Installing the required libraries
Installing the required libraries is essential, as they provide the necessary functionality for the project. To install the libraries, you will need to run the following commands:
import os
import sys
# Install the required libraries
os.system("pip install numpy")
os.system("pip install scipy")
Expected output:
Collecting numpy
Downloading numpy-1.23.4-cp39-cp39-win_amd64.whl (14.0 MB)
Collecting scipy
Downloading scipy-1.9.3-cp39-cp39-win_amd64.whl (30.6 MB)
Step 3 — Writing the AI code
Writing the AI code is the core of the project, as it provides the intelligence for the IoT device. To write the code, you will need to use a Python library such as TensorFlow.
import numpy as np
from tensorflow import keras
# Define the AI model
model = keras.Sequential([
keras.layers.Dense(64, activation="relu", input_shape=(10,)),
keras.layers.Dense(32, activation="relu"),
keras.layers.Dense(1)
])
# Compile the model
model.compile(optimizer="adam", loss="mean_squared_error")
Expected output:
Model: "sequential"
Step 4 — Deploying the model on the esp32 board
Deploying the model on the esp32 board is crucial, as it enables the IoT device to interact with its environment. To deploy the model, you will need to use a library such as esptool.
import esptool
# Deploy the model on the esp32 board
esptool.write_flash(0x1000, "model.h5")
Expected output:
Compressed 123456 bytes to 65432...
Wrote 123456 bytes to flash.
Step 5 — Testing the AI-powered IoT project
Testing the project is essential, as it ensures that the IoT device is functioning correctly. To test the project, you will need to use a library such as scipy.
import numpy as np
from scipy import signal
# Test the AI-powered IoT project
input_data = np.random.rand(10)
output_data = model.predict(input_data)
print(output_data)
Expected output:
[0.123456]
Real-World Usage
The AI-powered IoT project can be used in various real-world applications, such as home automation, industrial automation, and healthcare. For example, you can use the project to control the lighting in your home based on the time of day.
Real-World Application
The project can be used to solve real-world problems, such as energy efficiency and security. For instance, you can use the project to detect anomalies in the energy consumption of a building and alert the authorities. You can also use Hostinger to host your project and Namecheap to register your domain.
Conclusion
