We Know Soil Moisture.

Decagon Sensors


Our work horse soil moisture sensor. Measures Volumetric Water Content only. Just 5 cm long with a 0.3 L measurement volume, this handy little sensor is easy to ec5install in the field and can also be used in nursery pots. The EC-5 delivers research-grade accuracy at a price that makes large sensor networks economically practical. With the EC-5, you can adequately characterize your site with sensors at multiple depths and locations.


At 10 cm long, this sensor measure volumetric water content in a larger soil sample. The 10HS has a 1 liter volume of influence. High frequency oscillation and 10hspatented signal filtering deliver excellent accuracy and minimal textural effects. If you are focused on water content only and are interested in a large volume of influence, this sensor is more than capable.


Our full-featured soil moisture sensor, the 5TE measures volumetric water content, temperature, and electrical conductivity in soil. This three-pronged, 5 cm long 5tesensor is for use in soil only. High frequency oscillation and patented signal filtering deliver excellent accuracy with minimal textural effects. If you need to measure volumetric water content, electrical conductivity, and/or temperature, and if you are managing salts in your system, this is the sensor you are looking for.


Get temperature data integrated with your soil moisture data—at the same location and over the same measurement intervals. The 5TM is ideal for adding temperature to 5tmeach measurement site. The 5TM is ideal if you are interested in mechanisms that are affected by temperature or if you anticipate temperature change in your soil.


The GS1 is a ruggedized version of our basic, no-frills soil moisture only sensor. It accurately measures volumetric water content in soil or soilless media. gs1The longer lifetime of the GS1 helps your budget go a long way. It delivers research-grade accuracy at a price that makes large sensor networks economically practical. Characterize your site with sensors at multiple depths and locations, even if you’re on a tight budget.


The GS3 soil moisture, temperature, and EC sensor is the first sensor in the Decagon family that uses an epoxy body and stainless steel needles. gs3The internal circuitry is the same cutting edge design that you’ll find in other Decagon soil moisture sensors, but the form factor has been optimized for use in soilless substrates or harsh environments, giving it a wider range of EC measurement and an increased temperature range.


The MPS-2 measures a wide range of soil water potentials (-10 to -500 kPa (pF 2.01 to pF 3.71)) without user maintenance and factory calibration.MPS-2 Unlike tensiometers, which need a skilled operator, this dielectric water potential sensor needs no care or feeding. Instead, it can simply be packed into a hole, plugged into a data logger, and left to log water potential data.


The MPS-6 is a matrix water potential sensor that provides long term, maintenance-free soil water potential and temperature readings at any depth without sensitivity to salts. MPS-6 The range of the MPS-6 goes from field capacity to air dry. Lab and field tests indicate that it can make accurate measurements at water potentials at least as dry as permanent wilting point.
