Enviro+ Community Edition

Environmental monitoring for Raspberry Pi - Measure air quality (gases and particulates), temperature, pressure, humidity, light, and noise.

🌍 Join the Open Sensor Network

opensensor.space is a cloud-native platform for streaming environmental sensor data to open datasets.

Part of the walkthru.earth initiative for people-first urban intelligence:

• 🌱 Minimum carbon footprint - Edge processing reduces transmission by 60-90%
• 📊 Open data - All readings stored in Parquet format on Source Cooperative
• ⚡ Near real-time - Query sensor data in the browser with DuckDB
• 🔄 Resilient - Offline-first with automatic sync

🚀 Quick Start

Installation

# Install UV (if not already installed)
curl -LsSf https://astral.sh/uv/install.sh | sh

# Create isolated environment and install package
uv venv
source .venv/bin/activate  # On Windows: .venv\Scripts\activate
uv pip install enviroplus-community

# Check system requirements
enviroplus-setup --check

# Install system dependencies and configure hardware
sudo enviroplus-setup --install

# Reboot (required for hardware changes)
sudo reboot

Run Examples

# List all available examples
enviroplus-examples

# Get details about a specific example
enviroplus-examples --info weather.py

# Copy examples to your project
enviroplus-examples --copy ~/my-sensors/

# Run an example
uv run python -m enviroplus.examples.weather

# Or run directly (if venv is activated)
python -m enviroplus.examples.weather

Quick Test

import time
from pimoroni_bme280 import BME280

try:
    from smbus2 import SMBus
except ImportError:
    from smbus import SMBus

bme280 = BME280(i2c_dev=SMBus(1))

while True:
    temperature = bme280.get_temperature()
    pressure = bme280.get_pressure()
    humidity = bme280.get_humidity()

    print(f"Temperature: {temperature:.1f}°C")
    print(f"Pressure: {pressure:.1f}hPa")
    print(f"Humidity: {humidity:.1f}%")
    print("---")

    time.sleep(2)

🛠️ Hardware Setup

The enviroplus-setup tool automatically configures your Raspberry Pi:

# Check what's needed
enviroplus-setup --check

# Install and configure everything
sudo enviroplus-setup --install

What it does:

• ✅ Installs system packages (python3-cffi, libportaudio2)
• ✅ Enables I2C interface (for sensors)
• ✅ Enables SPI interface (for LCD display)
• ✅ Configures serial/UART (for PMS5003 sensor)
• ✅ Adds device tree overlays to /boot/firmware/config.txt
• ✅ Creates backup before changes

Note: A reboot is required after hardware configuration.
