Altitude click features the MPL3115A2 MEMS pressure sensor, which provides accurate pressure/altitude (20-bit) and temperature (12-bit) data. Resolution is down to 30 cm (1.5 Pa). The MPL3115A2 contains automatic internal data processing with data acquisition and compensation. It features a 32 sample FIFO buffer to minimize the overhead of collecting multiple data samples. It can autonomously collect data at programmed intervals and store it up to 12 days depending on data acquisition rate (1 second - 9 hours). The board uses an I2C communication interface and is designed to use a 3.3V power supply only. |
