Adafruit MPL115A2 Barometric Pressure Sensor Breakout
Overview
The Adafruit 992 is a breakout board featuring the Freescale MPL115A2 barometric pressure sensor, designed for precise atmospheric measurements and altitude tracking. It provides an I2C interface for easy integration with 3.3V or 5V microcontrollers and includes onboard level shifting and regulation.
Why Choose This Part
The board includes a 3.3V regulator and level-shifting circuitry, making it plug-and-play with both 3.3V and 5V logic levels. Its small form factor and I2C communication simplify the wiring process for rapid prototyping on breadboards.
Applications
Getting Started
Connect the sensor to your microcontroller via the SDA and SCL pins and use the Adafruit_MPL115A2 library available in the Arduino Library Manager. Ensure you call the calibration coefficients from the sensor's internal ROM to achieve accurate compensated pressure readings.
