Overview
Learn how to create a portable barometric pressure weather station in this 56-minute tutorial using the Arduino Uno R4 WiFi. Follow along as Paul McWhorter demonstrates how to build a weather monitoring system using the GY-87 sensor module with BMP180 pressure sensor and SSD1306 OLED display. The project displays real-time barometric pressure in inches of mercury (inHg), normalized to sea level to match official weather reports, along with a 24-hour pressure trend graph that helps predict weather conditions - rising pressure indicates fair weather while falling pressure signals approaching storms. This practical project is designed to be accessible for both beginners and experienced Arduino users, providing a functional weather monitoring tool you can take anywhere.
