SparkFun Altitude/Pressure Sensor Breakout - MPL3115A2

The SparkFun Altitude/Pressure Sensor Breakout - MPL3115A2 is a high-precision MEMS pressure sensor that can provide altitude data accurate to within 30cm when oversampling is enabled. The sensor's outputs are digitized by a high-resolution 24-bit ADC and transmitted over I2C, making it simple to interface with most controllers. The device can output pressure in fractions of a Pascal and altitude in fractions of a meter. It also provides 12-bit temperature measurements in degrees Celsius. This breakout board simplifies prototyping with this compact device by breaking out the necessary pins to a standard 2.54mm spaced header. The board includes all the passive components required for the device to function, so it can be easily connected to an I2C-compatible device to start operation.Features:

* Supply Voltage: 1.95V to 3.6V, internally regulated by LDO * Digital Interface Supply Voltage: 1.6V to 3.6V * Fully internally compensated * Direct Reading, Compensated: Pressure (20-bit measurement in Pascals), Altitude (20-bit measurement in meters), Temperature (12-bit measurement in degrees Celsius) * Programmable Events * Autonomous Data Acquisition * Resolution down to 30 cm * 32 Sample FIFO * Capability to log data for up to 12 days using the FIFO * Data acquisition rate from 1 second to 9 hours * I2C digital output interface (operates up to 400 kHz) The MPL3115A2 sensor can be used in a variety of applications. For instance, it can be integrated into weather stations for accurate pressure and altitude readings. It's also suitable for use in drones or other unmanned aerial vehicles (UAVs) where precise altitude data is critical. Its high-resolution output and autonomous data acquisition make it an excellent choice for scientific research and data logging applications.With its programmable events and ability to log data for up to 12 days using the FIFO, the MPL3115A2 sensor offers flexibility and convenience for long-term data collection.
