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 is the best low-cost, precision sensing solution for measuring barometric pressure with+/-1 hPa absolute accuracy, and temperature with +/-1.0Degrees Celsius 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
Typical applicationEnhancement of GPS navigation
e.g.time-to-first-fix improvement,dead-reckoning,slope detection
Indoor navigation(floor detection,elevator detection)
Outdoor navigation,leisure and sports applications
Health care application(e.g. sirometry)
Vertical velocity indication(e.g. risk/sink speed)
Handsets such as mobile phones ,table PCs,GPS devices
Portable health caredevices
Home weather stations
