MS5561-C是一个SMD模块，包括一个压力传感器和一个模数转换电路，及ADC介面IC，採用3线的接口通信。该模块尺寸小巧，平面只有4.75mmx 4.25mm，厚度只有1.6mm，切合時下新的SMD設計。它依靠電壓值提供16 bit的壓力及氣溫數據。MS5561-C配合自動省電開關，是一個低電壓及低電量的零件，使用3線接口介面與芯片作所有通訊連繫。

The MS5561-C is a SMD-hybrid device including a precision piezo-resistive pressure sensor and an ADC-Interface IC. It uses a 3-wire interface for communication. The module dimensions of 4.75 mm x 4.25 mm and a height of only 1.6 mm allows for up-to-date SMD design. It provides a 16 bit data word from a pressure and temperature dependent voltage. The MS5561-C is a low power, low voltage device with automatic power down (ON/OFF) switching. A 3-wire interface is used for all communications with a micro-controller.
