Soil Moisture
Soil Water Content Measurements
Soil moisture sensors also provide water management information. They can be added to weather/evapotranspiration stations or used independently. Both Campbell Scientific and Onset offer a wide variety of options for measuring soil moisture. Also see Sentek Technologies’ offering for complete soil monitoring systems.
For portable water content measurements, the hand-held HydroSense® II probe and display can be easily carried from site to site. The new HS2 handheld has been designed to be compact and portable, with the layout of the buttons allowing for operation with one hand. It shows real time soil-water content measurements in the field. Low power requirements allow thousands of measurements powered only by 4 AA batteries.
HOBO MX Soil Moisture and Temperature Data Logger
These low-cost, fully integrated Bluetooth soil moisture loggers provide accurate data to help researchers and growers conserve water, improve crop yields, and reduce harmful runoff to protect ecosystems. Available in two models: the HOBO MX2306 that measures soil moisture and the HOBO MX2307 that measures both soil moisture and temperature.
MX2306
MX2307HOBOnet Multi-Depth Soil Moisture Sensor
A wireless sensor that measures soil moisture and temperature at multiple depths with a single probe for easy installation. The new models offer better performance and consume less power. Works with the HOBOnet system.
Weather Stations and Evapotranspiration Stations
Evapotranspiration stations help provide an accurate method of estimating crop water needs to eliminate under- and over-watering, which saves money and improves crop quality. These automated stations calculate ETo using the Penman-Monteith equation. The output provides daily estimates of water needs. A low-cost, preconfigured station can calculate ETo from a reduced set of sensors.
Sentek Soil Probes
Sentek Technologies offers a suite of soil monitoring probes that measure soil moisture, temperature, and salinity at multiple depths concurrently. The data can be collected manually, or broadcast over radio or internet to your computer.
