ESP32 Smartdisplay Demo

Abstract

1. Introduction

This is a demo application for the esp32-smartdisplay library that is intended to be used in PlatformIO. See https://github.com/rzeldent/esp32-smartdisplay for more information about the driver library.

Example with sound! (if WiFi credentials are provided and speaker attached)

2. Objective

This project shows how to use the esp32-smartdisplay library

This project demonstrates how C++, ESP32 can be applied to a real-world Internet of Things (IoT) problem.

4. Technology Stack

5. System Requirements

General requirements for this technology stack — check the README for exact versions.

• Arduino IDE / PlatformIO or a C++ compiler (g++)
• Target board (e.g. Arduino, ESP32) where applicable
• Git (to clone the repository)

6. Installation & Setup

git clone https://github.com/rzeldent/esp32-smartdisplay-demo.git
cd esp32-smartdisplay-demo

Full setup instructions are in the project README.

7. Future Enhancements

Suggested extensions you can add to make this your own project.

• Add a mobile dashboard using Blynk or Firebase
• Store readings in a cloud database for history charts
• Add alerts via SMS / Telegram when thresholds are crossed

8. Viva / Review Questions

Common questions examiners ask for projects in this domain.

1. Which microcontroller / board and sensors are used and why?
2. How does the device send data (Wi-Fi, MQTT, HTTP, Bluetooth)?
3. Where is the sensor data stored and visualised?
4. How is power consumption managed?
5. How would you secure the device and its communication?
