Note

This part has been moved to the components section of the website http://developer.mbed.org/components/MPL115A2/.

MPL115A is a simple barometer with digital output and high performance targeting low cost commercial applications. The device employs a MEMS PRT pressure sensor with a conditioning IC to provide accurate pressure data. The sensor output is accurate to ±1 kPa over the 50 kPa to 115 kPa pressure range. An integrated ADC provides digitized temperature and pressure sensor outputs via an I2C or SPI bus. The part’s operating voltage is from 2.375 V to 5.5 V.

The part is available as either an I2C or SPI part.. However, the library on this page is for the I2C version.
