MS561101BA03-50 is a barometric pressure sensor with thin metal cap. The MS5611-01BA is a new generation of high resolution altimeter sensor from MEAS Switzerland with SPI and I2C bus interface. This barometric pressure sensor is optimized for altimeter and variometers with an altitude resolution of 10cm. The sensor module includes a high linearity pressure sensor and an ultra-low power 24bit ΔΣ ADC with internal factory calibrated coefficients. It provides a precise digital 24bit 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 microcontroller. The communication protocol is simple, without the need of programming internal registers in the device.
