MPL3115A2 - Digital Barometer, Pressure/Altitude Sensor Module - 110kPa I2C

The module with a digital barometer allows you to measure altitude in meters and pressure in the range of 20 to 110 kPa. The board has a built-in 20-bit analog-to-digital converter that converts the analog signal into digital form. Data is transmitted to the microcontroller via the I2C bus (TWI) at a speed of up to 400 MHz. The sensor operates with voltages in the range of 2.5 V to 3.6 V. It can be operated directly by microcontrollers operating on these voltages, e.g. STM32Discovery, Arduino Pro Mini 3.3V or a Raspberry Pi minicomputer.
