IoT System with Raspberry Pi

This is a simple IoT (Internet of Things) system built using a Raspberry Pi, various sensors (moisture, temperature, humidity), and actuators (water pump, drip system). The system consists of three main components: a Back-end server, a Front-end interface, and the Raspberry Pi IoT device.

Components

MERN + Python

1. Backend

• Technology Stack: Node.js, MongoDB
• Description: The backend server is responsible for collecting data from the Raspberry Pi, handling user input via WebSocket, and storing data in a MongoDB database.

2. Frontend

• Technology Stack: React.js
• Description: The frontend is a user interface built with React.js, using WebSocket connections to communicate with the backend. It displays real-time data and allows users to interact with the IoT system.

3. IoT Device (Raspberry Pi)

• Technology Stack: Python
• Description: The Raspberry Pi runs a Python script to communicate with the backend via HTTP POST requests and WebSockets. It collects data from various sensors and can trigger actuators based on user commands.

Setup and Installation

To set up and run this IoT system locally, follow these steps:

1. Backend Setup:

   • Clone this repository.
   • Navigate to the server directory.
   • Install the required Node.js packages by running npm install.
   • Start the backend server with nodemon.

2. Frontend Setup:

   • Navigate to the client directory.
   • Install the necessary dependencies with npm install.
   • Start the frontend with npm start.

3. Raspberry Pi Setup:

   • Set up your Raspberry Pi with Raspbian OS.
   • Clone this repository on your Pi.
   • Navigate to the python-scripts directory.
   • Run the rpi-scripy-new script on your Pi.
   • Also you have to interface all the sensors with GPIOs of pi
     • you can also use Arduino to connect sensors and use serial communication between Pi and Arduino, code for this is in rpi-script in python-scripts directory
