SparkFun Altitude/Pressure Sensor Breakout - MPL3115A2 Boards, Sparkfun Originals, Weather Instrument Cables Each time 20-30 minutes isLife has its ups and downs, so why not measure them? The MPL3115A2 is a MEMS pressure sensor that provides Altitude data to within 30cm (with oversampling enabled). The sensor outputs are digitized by a high resolution 24 bit ADC and transmitted over I2C, meaning its easy to interface with most controllers. Pressure output can be resolved with output in fractions of a Pascal, and Altitude can be resolved in fractions of a meter. The device also
