Abstract

Owlos is an open-source Internet of Things (IoT) project. Open Source IoT firmware and toolset for ESP32 / ESP8266. It is built using HTML, ESP32, ESP8266, Arduino. The complete source code is publicly available on GitHub under the GNU General Public License v3.0, making it a useful reference for students building an Internet of Things (IoT) mini project or final-year project.

1. Introduction

Open Source IoT firmware and toolset for ESP32 / ESP8266

2. Objective

Open Source IoT firmware and toolset for ESP32 / ESP8266

This project demonstrates how HTML, ESP32, ESP8266 can be applied to a real-world Internet of Things (IoT) problem.

4. Technology Stack

HTMLESP32ESP8266Arduino
  • DHT11, DHT22, AM2301 — temperature & humidity
  • BMP280, BME680 — barometric pressure
  • CCS811 — eCO2 and TVOC
  • SI7021 — temperature & humidity
  • ADS1X15 — ADC (for analog sensors like MQ7, MQ135, photoresistor)
  • Stepper motors
  • LCD displays (LiquidCrystal I2C)
  • DS3231 RTC — real-time clock

5. System Requirements

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

  • A modern web browser
  • VS Code or any code editor
  • Git (to clone the repository)

6. Installation & Setup

git clone https://github.com/KirinDenis/owlos.git
cd owlos

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?

9. Source Code & License
