Soil Moisture Sensors
Soil moisture content is highly variable. Accuracy from a single site isn't enough to run an experiment. To make good soil water
content measurements, you need research quality soil moisture probes and you need a lot of them.
Decagon's soil moisture sensors are research grade probes at a price that lets you completely characterise your site.
Plug-and-log with the Em50 line of data loggers or integrate into other logger systems (including Campbell Scientific).
Environmental Sensors
Sonic Anemometer
Pyranometer PYR/PAR Sensor
Humidity/Temp & Pressure Sensor
The DS-2 is a two dimensional sonic
anemometer that measures wind speed
and direction. It is highly accurate and
effective even at low wind speeds.
Completely waterproof and designed for
continuous outdoor use. These sensors
measure either total solar radiation (PYR)
or Photosynthetically Active Radiation (PAR)
Accurate relative humidity readings require air
temperature readings taken at the same place
and time. The VP-3 takes both measurements
simultaneously for the best possible accuracy.

Leaf Wetness Sensor
High-Res Rain Gauge
Conductivity, Temp & Depth Sensor
The LWS approximates the thermal
mass and radiative properties of leaves
to closely mimic the wetness state of a
real leaf. It requires no painting or user
calibration, and it can detect ice
formation as well.
The ECRN-100 has two internal tipping
spoons which make this rain gauge very
sensitive, with one tip per 0.2 mm of rain.
The CTD Sensor continuously monitors
groundwater and surface water level changes
along with conductivity and temperature.

Environmental Sensors
Decagon Devices offer a wide range of research grade environmental sensors that allow you to keep track of rainfall, wind speed
and direction, solar radiation, humidity temperature and pressure, water level and temperature and even specfic and difficult to
measure parameters such as leaf wetness and ice formation. Adding these to your soil moisture and temperature data gives you
a far broader understanding of the environment at your chosen research site.
All of these sensors are literally plug-and-log with the Em50 line of data loggers or integrate into other logger systems (including
Campbell Scientific).
Data Loggers and Readout Devices
Em5B Analogue Logger
ProCheck Readout
The Em5b is a low cost,
five-channel mini-logger. It
powers and reads the EC-5
and 10HS soil moisture
sensors, the ECRN-50 and
ECRN-100 rain gauges, and
the ECT temperature sensor.
Designed for use over the
growing season, the Em5b
runs for 5-6 months on
4 AAA-size alkaline batteries
and has 46 kB of Flash Data memory (138 days at 1 scan per
hour). The Em5b comes with ECH2O utility software for
setting up and downloading data.
Plug in the handheld ProCheck to get
a real-time reading from any Decagon
sensor. Press a button to save readings.
Each reading includes sensor type, date,
time, raw value, calibrated value, and
calibration data.
The ProCheck lets you monitor a sensor's
reading as it is installed; readout values
help you detect installation problems
(poor sensor to soil contact, air pockets,
rocks, etc.) before you repack the hole.
Data stored can be downloaded in
EXCEL format with the included ECH2O
utility software.

Can it really be that easy?
Yes, all Decagon Data Loggers come complete with simple to use Windows based
utility software, used to set time, date, sensor type and logging intervals. Once set
all you have to do is plug in your chosen sensors and start collecting data.
Cellular Logger
Similar to the Em50 the
Em50G is fully compatible
with all Decagon sensors and
is designed for all weather use.
The Em50G uses a GSM cell
modem to send stored data
to a secure server up to six
times a day. You can then
access and download the
data anywhere you have an
internet connection.
The Em50 is a self-contained data logger
built to power, read, and log data from
five sensors. All Decagon sensors work
with the Em50; no programming is
necessary. The logger itself is rated
NEMA 4, IP55 for long-term outdoor use,
and the logger will run and power its
sensors for one to three years, depending
on your measurement interval, on 5 AA

Monitor the Normalised Difference Vegetation Index or the Photochemical Reflectance Index.
NDVI and PRI are calculated as the ratio between reflected and incident radiation, measured using downlooking and uplooking sensors,
respectively. Depending on ambient sky conditions, one uplooking sensor may be able to provide reference values for multiple
downlooking sensors.
Uplooking SRS sensors have a hemispherical view with Teflon diffusers providing a cosine corrected response. They should be mounted
above the canopy with an unobstructed view of the sky.
Downlooking sensors are equipped with field stops that restrict the field of view of the SRS to 20°. The field stops allow you to aim the
sensor at a specific target and exclude non-canopy elements, such as a tower infrastructure, from the field of view.
The sensor can be mounted to monitor single plants, row crops, plots or forest stands.
Using the SRS sensors it
is possible to monitor
canopy variables such as:
• Light use efficiency (LUE)
• Biomass and crop yield
• Crop and forest phenology
• Canopy growth
• Photosynthetic

The Vapour Sorption Analyzer (VSA) brings click-and-read
efficiency to soil water characteristic curves (SWCC).
In 24 to 48 hours, the VSA generates curves with up to
200 data points (water potential vs. water content)
for both adsorption and desorption.
The VSA works in the dry (-10 to -475 MPa)
range. You can create automated soil
water characteristic curves and
generate all the correlations with clay
activity, surface area and swelling potential.
With the new static feature, you can hold
humidity constant and look at the way
soil takes up water into its crystal
structure (2:1 clays) and monitor
water content change over time.
