ES1101 – Soil Moisture and Soil Temperature The eS1101 Watermark Sensor (granular matrix sensor) is a soil moisture and soil temperature sensor. We recommend at least 2 eS1101 sensors be connected to one eKo Node to measure soil moisture at different soil depths. By monitoring the sensor measurements between irrigations, it is possible to measure the rate at which the soil is drying out.

ES1110 – Soil Water Content The ES1110 uses the Decagon EC-5 which obtains volumetric water content by measuring the dielectric constant of the media through the utilization of capacitance/ frequency domain technology. It incorporates a high frequency oscillation which allows the sensor to accurately measure soil moisture in any soil with minimal salinity and textural effects.

ES1201 – Ambient Temperature and Humidity The ES1201 is a temperature/humidity sensor that measures the ambient relative humidity and air temperature. These readings are also used to calculate dew point. The sensor enclosure protects the sensor from mechanical damage, and a membrane flter protects the sensor elements from dust, dirt, and water spray

ES1301 – Leaf Wetness The ES1301 is the leaf wetness sensor from Decagon. Many fungal and bacterial diseases affect plants only when moisture is present on a leaf surface. The ES1301 determines the presence and duration of canopy wetness allowing users to forecast disease and protect the plant canopy. Algorithms have been integrated into the eKoView interface to allow users to quickly determine if disease conditions are present

ES1401 – Solar Radiation The ES1401 uses the Davis Solar Radiation sensor and measures global radiation, both the direct and diffuse components of solar irradiance. Allows users to monitor evapotranspiration. Algorithms have been integrated into the eKoView interface allowing users to easily manage and make decisions based on the data collected for disease modeling and prediction.

ES2000 –Weather Station Sensor Suite The ES2000 offers an integrated weather sensor suite which combines a rain collector, a temperature and humidity sensor with radiation shield, solar radiation sensor, barometric pressure sensor and an anemometer in one package. The data collected allows users to display ET (evapotranspiration) data, do weather forecasted, calculate chill hours, heat degree days and dew point. The eKo node must be purchased seperately

Each eKo Node can support up to four sensors. Sensors are simply plugged into the unit, and when the eKo Node is reset, it scans the sensor ports to auto-identify the sensors. The Nodes are designed to accommodate almost any type of low-power sensor and allow for future support of many sensors. Its plug-and-play Environmental Sensor Bus (ESB) architecture provides the versatility to interface both smart and custom sensors, with direct plug-in for any 2 or 3-wire sensors.
