HS2 and HS2P 

to create a new zone will be presented.  If a zone already exists, data are 

attributed to that zone.  

The 

 function stores volumetric water content values.  Make 

a measurement before pressing the 

 button. 

8.2  What is stored? 

The flash file system holds the water content data file, the zone table, and the 

table of configuration settings.  The most important among these is the water 
content data file.  When the user stores a measurement by pressing 

, the 

most recent measurement of volumetric water content (VWC) is stored with 

the measured period, sensor type, current date and time, and latitude and 

longitude (if GPS synchronization has been achieved).  If the GPS is switched 

off or does not have a valid synchronization, system time and date are used 

without GPS confirmation of their accuracy.  When the GPS is disabled, check 

and adjust the system clock before storing data.  

The water content data file is configured as ring memory and is large enough to 

hold over 1000 values.  When the file becomes full, the oldest data are 

overwritten and storage continues. 

The zone data file is configured as fill-and-stop memory.  It holds a list of 

zones that have been created.  Zones are created whenever a datum is stored in 

a new location.  Each zone record contains the center position (latitude and 

longitude), radius in meters, and the zone name.  The zone file is large enough 

to hold over 100 zones.  When the zone data file is full, a new zone cannot be 

created until an old zone is removed. 

The configuration settings file is managed automatically.  These settings are 

synchronized to the computer where they can be viewed, modified, backed up, 

and restored.  For more information, please refer to the HydroSense II Support 

Software user guide. 

8.3  Software 

The HydroSense II ships with the latest version of the HydroSense II Support 

Software on CD.  For the latest version, please contact Campbell Scientific.  

For a complete guide to the use of this software, please refer to the HydroSense 

II Support Software user guide. 

8.4  Connecting via Bluetooth 

Steps to achieve a Bluetooth connection: 

 

Start HydroSense II Support Software. 

 

Turn on the HydroSense II display by holding the 

 button for 3 

seconds. 

 

In HydroSense II Support Software, click the Discover button to find 

Bluetooth devices within range. 

 

When the HydroSense II unit is discovered, click the “Connect” button.
