BMP280 Pressure Sensor Module

This sensor is great for all sorts of weather sensing and can even be used in both I2C and SPI.

This precision sensor is the best low-cost, precision sensing solution for measuring barometric pressure with 1 hPa absolute accuracy, and temperature with 1.0C accuracy. Because pressure changes with altitude and the pressure measurements are so good, you can also use it as an altimeter with 1 meter accuracy
