MS5540-CM is a SMD-hybrid pressure sensor which is a combination of piezoresistive pressure sensor and an ADC IC. The MS5540-CM provides a built-in 16-bit ADC resolution that will give you great precision over any pressure changes received by the sensor. For communication with microcontroller, MS5540-CM provides 3-wire interface. One interesting thing is that this sensor has been protected by a unique gel layer that is claimed to provide waterproof capability to a depth of 100 meters without the need for additional protection.
