Raspberry Pi Weather Station

Overview

In this project, you will build a simple weather station using a Raspberry Pi and environmental sensors. The station will measure temperature and barometric pressure, displaying the readings on a connected display.

What You Will Learn

• Setting up a Raspberry Pi with sensors
• Reading I2C sensor data with Python
• Displaying real-time data on a screen
• Basic data logging to CSV files

Step 1: Hardware Setup

Connect the BMP585 temperature and pressure sensor to your Raspberry Pi using the I2C pins (SDA and SCL). The sensor uses the Qwiic/STEMMA QT connector for easy plug-and-play wiring.

Step 2: Software Installation

Install the required Python libraries using pip. You will need the adafruit-circuitpython-bmp3xx library for the sensor and a display library if using an external screen.

1. Enable I2C in raspi-config
2. Install CircuitPython libraries
3. Run the test script to verify sensor readings

Step 3: Display and Logging

Connect the display and write a Python script that reads sensor data every 30 seconds, shows it on screen, and logs to a CSV file for later analysis.
