Life has its ups and downs, so why not measure? The MPL3115A2 is a MEMS pressure sensor that provides elevation data up to 30 cm (with oversampling enabled). The sensor outputs are digitized by a high-resolution 24-bit ADC and transmitted via I2C, so that an easy connection to most controllers is possible. The printed output can be resolved with the output in fractions of a Pascal, and the height can be resolved in fractions of a counter. The device also offers 12-bit temperature measurements in degrees Celsius.
This breakout board makes it easy to create a prototype with this tiny device by pulling out the necessary pins at a standard 0.1" distance from the header. The board also has all the passive components needed to make the device functional, so you can easily connect it to something that I2C speaks and can go to work!
