BMP280 High Precision Atmospheric Pressure Sensor Module for Arduino

• 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

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/0.60"*0.47"
