BMP280 3.3V Digital Barometric Pressure Altitude Sensor I2C SPI

• 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 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 accurac

Typical application:

• Enhancement 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
• Weather forecast
• Health care application(e.g. sirometry)
• Vertical velocity indication(e.g. risk/sink speed)
• Target devices
• Handsets such as mobile phones ,table PCs,GPS devices
• Navigation systems
• Portable health caredevices
• Home weather stations
• Flying toys
• Watches
• PCB size:(L*W)1.52* 1.20cm
