GY-BMP280 high precision atmospheric pressure sensor

Bosch has stepped up their game with their new BMP280 sensor, an environmental sensor with temperature,
barometric pressure that is the next generation upgrade to the BMP085/BMP180/BMP183. This sensor is great
for all sorts of weather sensing and can even be used in both I2C and SPI!
This precision sensor from Bosch is the best low-cost, precision sensing solution for measuring barometric pressure
with ±1 hPa absolute accuracy, and temperature with ±1.0°C 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
