BMP280 Digital Barometric Pressure Sensor Module 3.3V 5V For Arduino Replace BMP180

Features：

• 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

Applications：

• 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
