Adafruit Barometric Pressure / Altitude / Temperature Sensors - Adafruit 2651, The Adafruit BMP280 I2C or SPI Barometric Pressure / Altitude / Temperature Sensors use the next generation BMP280 sensor with an improved accuracy of ±1 hPa. They use only 2 x GPIO pins and provide you with precision air pressure measurements. Each board contains a 3.3V regulator, an I2C level shifter and pull-up resistors on the I2C bus making it 5V ready. The boards also support SPI which is handy if you want to use several sensors on the same bus. You can set the pressure sampling rate up to 128 samples per second to obtain a good averaged result whilst it's probably sufficient to sample temperature once per second.Adafruit supply a tutorial and library to get you started. The library also provides
a subroutine to calculate the altitude given the air pressure with a resolution of ±1m and a range of -500 to +9000m above sea-level. Though, if you're 500m below sea-level, you may want to use a different sensor. Supplied with a fully assembled and tested sensor board plus a strip of 0.1in. header pins for you to solder on as required.
