==Hardware==
The sensor board can be directly interfaced to the autopilots I2C 3.3V interface

==Usage==

To use the humidity sensor add:
{{Box Code|conf/airframes/myplane.xml|
<source lang="xml">
<modules>
<load name="humid_htm_b71.xml"/>
</modules>
</source>
}}

===Result message===

The raw data (ihumid/itemp) and the converted result (humid/temp) is written to the log file. The message is automatically sent when new data is received, it does not have to be added to the telemetry file.
{{Box Code|conf/messages.xml|
<source lang="xml">
<message name="HTM_STATUS" id="115">
<field name="ihumid" type="uint16"/>
<field name="itemp" type="uint16"/>
<field name="humid" type="float" unit="rel_hum" format="%.2f"/>
<field name="temp" type="float" unit="deg_celsius" format="%.2f"/>
</message>
</source>
}}
