Description:

MPL3115A2 Altitude/Pressure/Temp Sensor Breakout

The sensor can directly output accurate 20-bit pressure reading or 20-bit height reading, and 12-bit temperature reading, the effective resolution is up to 30 cm. From the measurement start to the international standard unit output (Pascal, meters, and degrees Celsius), MCU only need to read and write I2C operation, does not require any additional data processing, can effectively save MCU resources and greatly reduce system power consumption at the same time.

MPL3115A2 also supports on-chip pressure, height and temperature offset adjustment, autonomous data acquisition, limit alarm, and extreme records and other functions. The sensor also provides up to 128 times the oversampling rate, 32 FIFO sampling buffer for data storage, the host can read data as needed.
