Step 1: Set Up Your Raspberry Pi

1. Install Raspberry Pi OS:

   • Download and install the latest Raspberry Pi OS onto an SD card using the Raspberry Pi Imager.

2. Set Up Network and SSH:

   • Boot your Raspberry Pi.
   • Connect it to your Wi-Fi network via the desktop or manually configure Wi-Fi in /etc/wpa_supplicant/wpa_supplicant.conf (if headless).
   • Enable SSH for remote access:

   Select Interface Options > SSH > Enable.

    ```bash
    sudo raspi-config
    
    ```
   

Step 2: Install System Dependencies

1. Update your system:

   sudo apt update && sudo apt upgrade -y
   
   

2. Install required dependencies:

   sudo apt install python3 python3-pip python3-venv git -y
   
   

Step 3: Set Up the Project Directory and Virtual Environment

1. Create a project directory:

   mkdir ~/py-sds011 && cd ~/py-sds011
   
   

2. Set up a virtual environment:

   python3 -m venv myenv
   source myenv/bin/activate
   
   

3. Install required Python packages inside the virtual environment:

   pip install flask chart-studio sds011 psutil
   
   

Step 4: Connect the SDS011 Sensor

1. Plug in your SDS011 sensor via USB.
