BMP280 I2C SPI Digital Barometric Pressure Sensor Module for Arduino

The BMP280 sensor is 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.
BMP280 pressure sensor is designed for mobile applications.The sensor module is to use a very compact package.Its small size and low power consumption to allow the battery power supply devices such as mobile phone, GPS module, or a watch. BMP280 proven piezoresistive pressure sensor technology has high precision, high linearity and long-term stability and robustness of electromagnetic compatibility.Many devices operating option provides flexibility and optimize the power consumption device, resolution and filter performance.

Features:
- Pressure range: 300 ~ 1100hPa (altitude 9000 m ~ -500 m);
- Working voltage: 1.71 - 3.6VDC;
- Low power consumption: 4μA;
- High precision: at low-power mode, the resolution is 0.06hPa (0.5 meters);
- Temperature output;
- Communication interface: I2C or SPI;

Application

GPS navigation enhancement (such as time the improvement of ap, navigation calculation, slope detection)
Indoor navigation (ground test, elevator testing)
The application of the navigation of outdoor, leisure and sports
The weather forecast
The application of the health care (such as spirometry)
Vertical speed indicator (such as rising or sinking speed)
Applications such as weather forecast, elevation measurement, indoor navigation, fitness and sports, etc.Digital pressure sensor BMP280 can provide excellent performance, relative accuracy of plus or minus 0 12 hPa (+ / - 1 m).

Note: You need to add 5V to 3.3V level converter circuit between Arduino UNO R3 and the module.
