Mongo Secure Climate Logger

Overview

The Mongo Secure Climate Logger is an IoT-based environmental monitoring system that captures real-time temperature, humidity, and heat index data. This project utilizes an ESP8266 microcontroller and a DHT11 sensor to collect data, which is then sent via Wi-Fi to a RESTful API built with Node.js and Express.js. The data is securely stored in MongoDB Atlas, ensuring scalability and persistence. Additionally, pfSense is used as a firewall solution to enhance network security.

Features

• Real-time temperature and humidity monitoring
• Data transmission via Wi-Fi using ESP8266
• REST API for data storage and retrieval
• Secure data storage with MongoDB Atlas
• Interactive visualization using ThingSpeak
• pfSense firewall integration for enhanced security

Technologies Used

• Hardware: ESP8266, DHT11 Sensor
• Software & Tools:
  • Programming Languages: JavaScript (Node.js)
  • Backend Framework: Express.js
  • Database: MongoDB Atlas
  • Firewall: pfSense
  • Data Visualization: ThingSpeak
  • Development Environment: Arduino IDE, VS Code

Installation & Setup

1. Clone the Repository

git clone https://github.com/yourusername/mongo-secure-climate-logger.git
cd mongo-secure-climate-logger

2. Install Dependencies

npm install

3. Configure Environment Variables

Create a .env file and set up your MongoDB URI:

MONGO_URI=mongodb+srv://yourusername:yourpassword@yourcluster.mongodb.net/IoT_db
PORT=5000

4. Run the Server

node new.js

The server will start at http://localhost:5000

5. Deploy the Arduino Code

• Upload the arduino_code.ino to your ESP8266 using the Arduino IDE.
• Ensure the Wi-Fi credentials and API endpoint match the server settings.

API Endpoints

Method	Endpoint	Description
POST	/api/sensors	Stores sensor data

Security Enhancements

• pfSense Firewall: Protects the REST API server and database.
• Encrypted API Calls: Ensures data integrity during transmission.
• MongoDB Security Rules: Restricts unauthorized access.
