Grove - BMP280 - Pressure and temperature sensor I2C/SPI

Product description: Pressure and temperature sensor BMP280

The pressure sensoris a module for a precision digital barometer that can be used to measuretemperature andatmosphericpressure.It is compatible with Arduino and connectsto itvia the I2C bus. BMP280 is an improved version of BMP180. The BMP280 sensor now has a smaller surface area, consumes less energy and measures much more accurately. TheSPIinterface allows more measurement modes. The module is veryeasy to connectand use, just connect the sensor with Arduino board using Grove cable. Examples of codes are given below in the library.
