University Institute of Engineering

Department of Computer Science & Engineering

Experiment No.: 3
Student Name: Anmol UID:25BAI70660

Branch: Computer Science & Engineering Section/Group:25AML108-A

Semester:1 Date of Performance:28/08/2025

Subject Name: Emerging & Disruptive Technologies Workshop

Subject Code: 25ECP-103

1. Aim of the Experiment:Design a voice-assistance Smart home automation system


using an IoT platform and relevant components.

2. Tools/Hardware Components/Software Used:ESP32 microcontroller, BMP280,


Breadboard, connecting wires, LED,USB cable.

3. Theory: This experiment shows a smart home system that works with voice control. A
custom app made with MIT App Inventor sends voice commands to the ESP32
microcontroller through the Ubidots IoT platform. The ESP32 then follows these
commands to control devices like a bulb or LED. This setup combines IoT and voice
technology to make modern homes smarter. The main goal is to control home
appliances from anywhere using cloud platforms, making life more convenient,
energy-efficient, and secure.

4. Code/Circuit Diagram/Procedure:
 Make the circuit as suggested.
 Now connect the circuit to CPU.
 Log into your Ubidots account and create a new device with the name of smart
home voice assistant. Create a new variable with the name of bulb.

 Now login to MIT App Inventor and design the app to take voice commands to
turn on the LED.

 Open the Arduino IDE and write the code for reading data from BMP280,
sending data to Ubidots and receiving commands from the App made.
 Compile the code and burn it to ESP32 microcontroller.
 Say the command to turn on the LED through the App.The LED should be
glowing.
5. Observations, Simulation Screen Shots, and Discussion:

The LED starts glowing after we say the command.

6. Result and Summary: A fully functional IoT-based Smart Home Automation


System was implemented, enabling voice monitoring and control using ESP32,
Ubidots, and MIT App Inventor.

7. Additional Creative Inputs (If Any): NIL


8. Learning outcomes (What I have learnt):

1. The process of integrating voice recognition into IoT systems using MIT App
Inventor.
2. Understanding the workflow of sending and receiving data between hardware
(ESP32) and software platforms.
3. Basics of sensor data acquisition (BMP280) and cloud-based monitoring.
4. Importance of IoT in making smart homes energy-efficient, secure, and user-friendly.
