Instantaneous Data Collectors


ProCheck: Plug in the hand-held ProCheck to get a real-time reading from any of Decagon’s sensors. ProCheck is often used to spot check soil moisture, but it can instantaneously read any soil moisture or environmental sensor. Press a button to save up to 5,000 individual readings. Each reading includes sensor type, date, time, raw value, calibrated value, and calibration coefficients.

EM50 Non-radio:


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 Em50 doesn’t need an enclosure or an external power source. The logger case 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 on 5 AA batteries. Data can be collected from the EM50 with a laptop or Field PC.

EM50R Radio:


The Em50R lets you download data without plugging into your data logger as long as you are within radio range*. The Em50R is a self-contained data logger built to power, read, and log data from five sensors. Logged data are transmitted via radio signal to a Decagon base station (DataStation or RM-1). All Decagon sensors work with the Em50R; no programming is necessary.



The Em50G is a self-contained data logger built to power, read, and log data from five sensors. Logged data are transmitted from the logger to Decagon’s server via internal cellular/mobile communication. All Decagon sensors work with the Em50G; no programming is necessary.

EC-5, Soil Moisture:


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 install 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.

10HS, Soil Moisture:


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 patented 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.

5TE, Soil Moisture, Temperature and Electrical Conductivity:


Our full-featured soil moisture sensor, the 5TE measures volumetric water content, temperature, and electrical conductivity in soil. This three-pronged, 5 cm long sensor 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.

5TM, Soil Moisture and Temperature:


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 each 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.

MPS-1, Water Potential Sensor:


The MPS-1 measures a wide range of soil water potentials (-10 to -500 kPa (pF 2 to pF 3.71)) without user maintenance and factory calibration. The MPS-1 has been used for deficit irrigation monitoring and control, water potential monitoring in the vadose zone, crop stress, waste water drainage studies, and plant water availability.

Leaf Wetness Sensor:


This sensor, that closely mimics the wetness state of real leaves, detects wetness and ice formation. Uses for the Leaf Wetness Sensor include predicting when to spray crops, quantifying water storage in the plant canopy, and studying and monitoring crops for foiliar diseases including rust and blight.

Rain Gauge ECRN-50:


The best rain gauge for measuring irrigation events. This durable,self-emptying gauge is made of UV, water and frost resistant plastic. The ECRN-50 can also be reconfigured to measure the output of irrigation systems in terms of gallons or liters per hour.

Rain Gauge ECRN-100:


The best rain gauge for measuring precipitating and for use in micro-climate monitoring. This durable gauge is made of UV, water and frost-resistant plastic.

ECT, Soil Temperature:


The simple ECT soil temperature sensor is an easy-to-use sensor for measuring the temperature of soil, air (with the radiation shield), or other materials. The sensor is completely water proof, submersible, and designed for continuous outdoor use.

EHT, Relative Humidity/Temperature:


This compact 3 cm x 1cm sensor Measures air temperature and relative humidity. The included radiation shield improves air temperature and relative humidity readings at the sensor’s location. Outputs both values as a digital signal.

PS-1, Pressure Switch:


Ads irrigation water on/off data into the soil moisture data set. This allows the user to track irrigation events with the rest of the soil moisture data by recording when water is turned on and off.

QSO-S PAR, Solar Radiation Sensor:


PAR is often used to generate interception, which is then used to predict biomass production, crop growth, etc. This simple, no-frills sensor measures photosynthetically active radiation over your chosen interval. 

PYR Total, Solar Radiation Sensor:


Total solar radiation data is used to calculate an energy balance, to distinguish between latent heat flux and sensible heat, and as in input in the Penman-Monteith equation, among other things. This simple, accurate sensor allows you to measure total solar radiation over your chosen interval.

Davis anemometer; Wind Speed and Direction:


measures wind speed and direction over your chosen measurement interval without complex setup, maintenance, or programming.

Radio Receivers/Transceivers


RM1 USB Transceiver


The RM1 USB transceiver can be attached to a laptop running DataTrac and used to query EM50R Loggers from the edge of a field. You can save collection time from widly distributed monitoring sites. You can also reduce disturbance of the monitoring site if you avoid walking to the logger for data collection. It is powered through the USB port of your laptop and can be connected to an optional magnetic mount antenna for increased range. Typically, the RM1 can connect to any EM50R within visual line of sight.

RM1 Serial Transceiver


The RM1 serial transceiver can be used as a repeater to increase the broadcast distance from an EM50 dataloggers to the DataStation. This application requires a constant power supply. The repeater should be mounted as high as possible with a clear line of sight to both radio loggers and the DataStation.



The Ech2o DataStation is an always on receiver with data storage capable of receiving data from up to 50 EM50R Loggers within 5 miles, line of sight. It incorporates a confirmed delivery protocol which increases the reliability of data transmissions for the EM50R Loggers. The DataStation can be connected directly to a PC via an RS232 serial connection.
