SensorShare3

A Raspberry Pi project for sensor data collection and sharing via MQTT, featuring light sensors (BH1750, VEML6075) and NeoPixel LED control.

Features

• Light Sensors: BH1750 and VEML6075 UV sensors for indoor/outdoor light measurement
• MQTT Communication: Real-time sensor data publishing and subscription
• NeoPixel Control: WS2812B LED strip control for visual feedback
• Motor Control: BuildHAT motor integration for physical actuators

Hardware Requirements

• Raspberry Pi (tested on Raspberry Pi 5)
• BH1750 light sensors (I2C)
• VEML6075 UV sensors (I2C)
• WS2812B NeoPixel LED strip
• BuildHAT (for motor control)

Installation

1. Clone the repository:

   git clone https://github.com/YOUR_USERNAME/SensorShare3.git
   cd SensorShare3

2. Run the installation script:

   chmod +x install.sh
   ./install.sh

   Or for NeoPixel-specific installation:

   chmod +x install_neopixel.sh
   ./install_neopixel.sh

3. Activate the virtual environment:

   source venv/bin/activate

4. Install Python dependencies:

   pip install -r requirements.txt
