This is a high precision pressure sensor based on the MS5611-01BA03 chip. The module comes with I2C and SPI interface breakout pins, so you can directly use it in your project.
The MS5611-01BA is a new generation of high resolution altimeter sensors from MEAS Switzerland with SPI and I2C bus interface. It is optimized for altimeters and variometers with an altitude resolution of 10 cm. The sensor module includes a high linearity pressure sensor and an ultra low power 24 bit ΔΣ ADC with internal factory calibrated coefficients. It provides a precise digital 24 Bit pressure and temperature value and different operation modes that allow the user to optimize for conversion speed and current consumption. A high resolution temperature output allows the implementation of an altimeter/thermometer function without any additional sensor. The MS5611-01BA can be interfaced to virtually any micro-controller. The communication protocol is simple, without the need of programming internal registers in the device.
