	The Measurement Specialties MS5611 is an excellent barometer/pressure sensor. Currently a plastic case version (-01BA01) and a metal case version (-01BA03) exist. The sensor can be used as I2C or SPI device. This page describes the connection through I2C (the MS5611 mounted on the Aspirin V2.2 uses the SPI port).		The Measurement Specialties MS5611 is an excellent barometer/pressure sensor. Currently a plastic case version (-01BA01) and a metal case version (-01BA03) exist, both with the same functionallity. The metal case was added since the values form the plastic one change under the influence of bright light. The sensor can be used as '''I2C''' or '''SPI''' device.

			This page describes the connection through '''I2C'''. Note that the MS5611 mounted on the Aspirin V'''2.2''' uses the SPI port, the Aspirin V'''2.1''' still '''I2C'''

	The device was tested in a simple static noise comparsion [[Baro_comparsion\|setup]].		The device was tested in a simple static noise comparsion [[Baro_comparsion\|setup]].

== Hardware ==

The sensor can directly interface to the 3.3V I2C port of the autopilots and is supplied by +3.3V.

== Usage ==

To use it load the baro_ms5611_i2c module:
{{Box Code|conf/airframes/myplane.xml|
<source lang="xml">
<modules>
...
<load name="baro_ms5611_i2c.xml"/>
</modules>
</source>
}}

=== Configuration ===

To see the sensors data in the log file set the SENSOR_SYNC_SEND in your airframe file. Every time new data is available it will be sent directly.
{{Box Code|conf/airframes/myplane.xml|
<source lang="xml">
<modules>
...
<load name="baro_ms5611_i2c.xml">
<define name="SENSOR_SYNC_SEND"/>
</load>
</modules>
</source>
}}

===Result message===

The raw values (d1/d2) and the corrected ones (pressure/temp) are written to the log file.
{{Box Code|conf/messages.xml|
<source lang="xml">
<message name="BARO_MS5611" id="116">
<field name="d1" type="uint32"/>
<field name="d2" type="uint32"/>
<field name="pressure" type="float" unit="hPa" format="%.2f"/>
<field name="temp" type="float" unit="deg_celsius" format="%.2f"/>
</message>
</source>
}}

The sensors calibration values are read out at init time and transmitted every 30 seconds. They can be seen as some sort of unique serial number.
