Bare Bone Sim800

Abstract

1. Introduction

The Purpose of This library is to use the SIM800 module providing core functionalities while still maintaining strong performance and being memory efficient.

This Library uses the AltSoftSerial Library instead of the SoftSerial Library to allow for compatibility with other PinChange Interrupts Library and SPI Libraries

2. Objective

A BareBone Arduino Library For SIM800 Modules

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

3. Key Features / Modules

• Send SMS, Read SMS and Delete SMS
• AT Command Test
• Send and Receive HTTP data
• TCP Connection
• IoT Applications
• Low power saving mode
• Location and Time Update

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/thehapyone/BareBoneSim800.git
cd BareBoneSim800

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?
