BMP180 Barometer Monitor
Sensors · Board: ESP32 · Day 50 of 100
Track atmospheric pressure and altitude with a BMP180 on the ESP32, visualized in Blynk. Weather forecasting hardware.

How it works
The BMP180 reports raw pressure over I2C, from which the ESP32 derives both sea-level-adjusted pressure and approximate altitude. Readings stream to a Blynk dashboard where trends — the falling pressure before a storm — become visible.
What you'll learn
- Barometric pressure sensing
- Altitude derivation
- I2C sensor interfacing
- Weather trend analysis
