Campbell HS2 HydroSense II Handheld Soil Moisture Sensor Description：

Datasheet User's Manual

The HS2 is the handheld display for the new Hydrosense II soil-water sensor. When paired with either the CS658 or CS659 portable soil-water probes, it replaces the previous Hydrosense soil-water system. It features a new handheld display and a new probe design. The HS2 handheld has been designed to be compact and portable, with the layout of the buttons allowing for operation with one hand.

The display consists of a three-inch LCD and four navigation buttons that make changing settings and taking measurements as easy as possible. An integrated GPS tags each measurement with a latitude and longitude.

Zones can be created on the unit which group measurements together so that average soil moisture can be calculated for an area. The current position and zone are shown on the display so that measurements can be taken in the same zone.

Data storage has been added to allow more than 1000 measurements to be stored on the device. The data can then be downloaded to a PC via Bluetooth for viewing and archiving.

The new soil moisture probe uses the same accurate measurement technique as the old probe, but the probe housing has been redesigned to aid insertion into and removal from hard soils. The probe rods are secured to the probe housing with ferrule nuts to provide extra stability during insertion. A molded plastic grip connects the sensor cable to housing to provide better grip.

New PC software has been developed to make the most of the data storage capability of the HS2. The software connects to the HS2 via Bluetooth to avoid the need for extra cables.

The software allows the user to:

View data in table and chart views

Edit zone positions and sizes

Change device settings

Export data to CSV to interface with 3rd party software

View zones and measurements in Google Earth
