HS2 and HS2P
NOTE
NOTE
CAUTION
The HydroSense II is an easy-to-use, portable device for measuring volumetric
water content of soil. The major components of the system are the display, the
sensor, and the software. A sensor with 12 cm rods (model CS659 or CS659P)
and a sensor with 20 cm rods (model CS658 or CS658P) are available.
Campbell Scientific offers the HS2, the standard HydroSense II system, and
the HS2P, a HydroSense II system with a strong handle and pole. FIGURE
1-1, HS2 HydroSense II System (p. 1) shows the HS2 and FIGURE 1-2, HS2P
HydroSense II Pole System (p. 1) shows the HS2P.
Throughout the manual, HydroSense II refers to both the HS2 and
HS2P, unless specified otherwise.
2. Cautionary Statements
• The connectors that connect the HydroSense II display to the sensor are a
push-pull type with locators to align the connectors. DO NOT TWIST.
The connectors can be damaged if the user twists them or attempts to
screw or unscrew them.
• Remove the AA batteries before putting the HydroSense II display into
storage.
3. Quickstart
• An unobstructed view of the sky may be required to achieve the most
accurate global position data possible from the HydroSense II GPS.
• Sensor rods must be completely inserted into the soil before making a
measurement.
1. Remove the HS2 display or HS2P from the carry case.
2. Remove the blue protective strip from the display window.
Steps 3 and 4 are for the HS2 only because the HS2P comes fully
assembled. If using an HS2P, go directly to step 5.
3. Remove the HS2 sensor from the carry case.
4. Connect the HS2 sensor to the display by mating the connector on the
cable to the connector at the bottom of the display. DO NOT TWIST the
connectors.
The connector is a push-pull type with locators to align the
connectors. The connectors can be damaged if the user
attempts to screw or unscrew them. To mate the
connectors, simply bring them together and turn until they
are aligned, then applying firm pressure, slide them together
until they click. To disconnect, pull back on the connector
collar with the thumb and forefinger and pull the two
connectors apart.

5. Turn on the HydroSense II by holding the button for 3 seconds.
6. Establishing a GPS sync may take up to one minute or more. When the
GPS icon is displayed ( ), synchronization has been successful.
Measurements with GPS data can now be taken. See Appendix A.14, GPS
Settings (p. A-6) for information on toggling the GPS.
The HydroSense II stores positional information (when available),
time, and date with measurements. To reliably take advantage of
the GPS, use the HydroSense II outdoors with a clear view of the
sky. Measurements can be made and data stored without a
) signal; however, the HydroSense II Support Software
(p. 19
(HydroSoft) will be unable to later group and display data
geographically.
7. Insert the sensor rods fully into the soil. The HS2P uses a plastic
“bumper” that covers the rod mounting nuts. Insert the rods into the soil
up to the plastic “bumper”.
Only remove the plastic bumper when replacing soil rods and put
it back on when done.
GPS
4. Overview
8. To take a measurement, press . When the hourglass icon ( ) in the
lower right of the screen is extinguished, the measured VWC and period
are shown on the screen.
9. Press to store the measurement. Assuming the GPS is in sync, follow
the prompts to create a zone.
10. Data are now stored in memory. To retrieve data, first establish a
Bluetooth link with your PC, and then collect data using the HydroSense II
support software. See Section 8.4, Connecting via Bluetooth (p. 18) and
Section 8.5, Collecting Data (p. 19).
The HydroSense II is a portable system for measuring volumetric water content
of soil. It is an improved successor to the HydroSense. TABLE 4-1,

HydroSense II and HydroSense (I).

Unlike the HydroSense (I), the 12 cm and 20 cm rods of the
HydroSense II are not interchangeable.
The HydroSense II can display relative water content (RWC) based on wet and
dry references set by the user. The unit also displays water deficit, which
indicates how much water is required (in mm of applied water) to return the
soil to the previously saved wet reference.
Measurements are made by fully inserting the sensor rods into the soil and
pressing . The process takes 2 to 3 seconds. The measurement can be
stored and later downloaded to a computer for display and analysis.
Communications between the computer and HydroSense II are via Bluetooth
(p. 18). The HydroSense II includes a GPS (Global Positioning System)
(p. 19) receiver that enables data to be stored with position information
(geotagged (p. 19)).
The HydroSense II has these default power saving features:
• turns off when idle for a configurable period
• adjustable backlight brightness and on-time
4
• backlight automatically disabled in bright conditions
• GPS and Bluetooth can each be forced off.
