EnviroSCAN Soil Moisture Probe
EnviroSCAN Soil Moisture Probe. Sentek's flagship product offers remarkable flexibility in accurately and continuously monitoring water, temperature and salinity levels at various depths within a soil profile. Initially recognized for its significant contributions to irrigated agriculture, the EnviroSCAN probe has proven instrumental in achieving water savings of 30-50% and significant improvements in crop yield and quality. Today, its applications span multiple sectors of agriculture environmental monitoring, research and education, as well as turf management, parks and gardens. What sets the EnviroSCAN probe apart from other options on the market is that it is the only commercially available product that can monitor soil properties at considerable depths, up to 40 meters, with the convenience of a single profiling probe. Horizontal, fully buried installation of probes is also possible.
Contact us to discuss the application potential of the EnviroSCAN probes, especially when combined with automatic minirhizotron imaging to better understand short-term root and rhizosphere dynamics as driven by abiotic soil parameters (and vice versa).
EnviroScan Probe - Features
- Select specific sensors to continuously measure soil moisture, with the option to include salinity and/or temperature measurements.
- The system accommodates up to 16 sensors spaced 10 or more cm apart, allowing for adjustable depth placement. This allows monitoring at various depths, from shallow (0-10 cm) to deep installations (up to 40 meters).
- Individual sensors can be calibrated to specific soil characteristics for more accurate measurements.
- Probe lengths are flexible and can be customized for your specific application, with the ability to adjust the probe length in the field. The top of the access tube is sealed with either a flat or screw cap, depending on the application.
- To improve sensor repeatability, the probe has built-in orientation and depth settings.
- RTV silicone conformal coating for additional circuit protection. The system is fully field serviceable, allowing to easily replace and adjust sensors as needed.
- It provides flexible connectivity options to facilitate different methods of data retrieval.
EnviroScan Probe - Options
- Flatcap, and Screw Cap types (see below)
- Different wired connection types / communication protocols
-
- 5-wire probes for Sentek RT6,
- RS232 probes,
- RS485 probes,
- SDI-12 probes (for IoT)
- Freely configurable number of sensors, distances in readily available access tubes up to 2 m. Deep installation kits on request.
- Select Soil Moisture Sensor, TriScan Sensor (Moisture and Salinity), and/or a Humidity and Temperature Sensor, or combinations
Access Tube - Features
- Designed for long-term use, the system ensures durability and reliability.
- Protects sensors from direct soil contact, significantly extending sensor life.
- Convenient, hassle-free installation option that minimizes disturbance to the surrounding area. Option of selecting installation method of choice: pre-drilled, slurry or self-tapping holes
- Protruding, tightly sealed screw cap OR ground-level, watertight flat cap versions
- Improved sensor accuracy is achieved through precise wall thickness and diameter.
- Field service and maintenance are easily accessible, eliminating the need to remove the entire probe and preserving the integrity of historical data.
Scew Cap
- Top cap protrudes above the soil surface
- Easy to find and readily accessible
- Tightly sealed with a rubber O-ring
- Simply unscrews, giving easy access to the probe for servicing
Flat Cap
- Enables the probe to be positioned at ground level, seamlessly integrated with the soil surface.
- A water-tight, three-point sealing mechanism.
- Facilitates access to the probe for servicing.
- Helps prevent potential damage from machinery, minimizing the risk of costly repairs.
Sentek All-in-One - Data transfer unit per EnviroScan Probe
Sentek All-in-One Soil Moisture & Data Transfer. The solution integrates the EnviroSCAN probe with a built-in data transmission unit. This comprehensive solution enables the transmission of moisture, temperature (and salinity, TriScan version) data to the cloud via cellular networks, satellite. No matter where you are, you can count on consistent data delivery.
The All-in-One eliminates the need for external wiring and solar panels, significantly reducing installation time while maximizing reliability. 0.5, 1.0, 1.5 m length available. Wireless data access is available on smart or Windows devices via Bluetooth connectivity. The unit is powered by a high-capacity lithium battery pack that can power the probe for 12–24 months, depending on sampling and upload rates. When combined with Sentek's IrriMAX Live data viewer, the all-in-one becomes a powerful solution for precise irrigation control. IrriMAX Live allows users to access live data on any Internet-connected device, providing flexibility and accessibility from anywhere at any time.
