Altimeter Absolute Pressure Sensor MS5561
Pressure Medium: Air/Gas
Sensor Type: Absolute, Barometric
Supply Voltage: Under 5V
Output Signal: Digital
Pressure Range: 3-300 psi
Kind: Board Level

The MS5561 is a SMD-hybrid device including a precision piezoresistive pressure sensor and an ADC-Interface IC. It uses a 3-wire serial 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 is a low power, low voltage decide with automatic power down (ON/OFF) switching. A 3-wire interface is used for all communications with a micro-controller.
