SoilMoisture - Soil Water Samplers
Soil water samplers, also known as soil solution samplers, are devices used to collect water from the soil for analysis. Such analysis can be performed onsite or by a lab. This water (soil solution) contains nutrients, salts, and other dissolved substances that are available to plants. By sampling this water, researchers and farmers can monitor nutrient availability, fertilizer efficiency, pollution levels, and general soil health.
SoilMoisture / Stevens - Soil Moisture Retention Curve Analysis
Developing soil moisture retention characteristics of a soil or soil moisture release curve is at the core of soil hydrology studies that aim to understand soil water-plant-atmospheric systems, recharge processes, enhance hydrological models used in climate studies, carbon respiration and sequestration processes, and more. A soil moisture retention curve (also called the soil water retention curve or soil water characteristic curve) is a graph that shows the relationship between the soil water content and the soil water potential (or matric potential). It describes how tightly water is held in the soil and how much water is available to plants or for other applications.Meteorology / Weather Sensors
Apogee - Accurately Measure Photosynthetically Active Radiation
Apogee Instruments’ Full-Spectrum Quantum PAR sensors and PAR meters are the industry standard for accurately measuring photosynthetically active radiation (PAR or PPFD) from all light sources used to grow plants and corals.
Apogee - Solar PAR Sensor
A solar PAR sensor (Photosynthetically Active Radiation sensor) is a device that measures the amount of light in the PAR wavelength range (400–700 nanometers), which is the portion of the light spectrum used by plants for photosynthesis. PAR is the light energy (in micromoles of photons per square meter per second, or µmol/m²/s) that plants can use to photosynthesize. Unlike total solar radiation sensors (which measure all sunlight, including infrared and UV), a PAR sensor focuses only on the light relevant to plant growth.Data Acquisition Platforms / Data Loggers
Stevens-Connect - AWS Cloud-based Data Management Software (SaaS)
Stevens-Connect is a cloud-based data acquisition and management software system that enables the collection, analysis, reporting, and storage of data from remote monitoring locations. As a cloud-based software-as-a-service (SaaS), Stevens-Connect streamlines the data management process and can be accessed from any computer or smartphone with Internet connectivity. Our cloud-based data integration hub is incredibly powerful and incredibly intuitive. It’s used to configure your sensors’ logging and reporting settings. It stores and analyzes your data, notifies your smartphone when conditions are met, allows you to visually create custom calculations and “virtual sensors”, and it can receive and/or forward data from/to 3rd-party systems. Stevens-Connect manages data from multiple locations and reduces the need for a localized data management software and data collection hardware.

Stevens - Soil Moisture Tempe Cell Analysis System
The Stevens Tempe Cell System can employ five different methods to eliminate the uncertainties from soil moisture measurements and achieve the highest level of accuracy. This system uses an enhanced gravimetric method to measure soil moisture to obtain the actual volumetric water content and develop a soil moisture calibration equation to validate and/or program into soil moisture sensors. In addition, the system’s outputted data can be used to develop a soil-specific calibration curve, and to develop an algorithm to determine the soil’s matric potential using the HydraProbe. The Stevens Tempe Cell is ideal for mesonets, climate reference networks, and soil monitoring stations.
