The SNiP-EC5 is a 'Sensor Node Integrated Package' for LoRaWAN communication of real-time soil moisture measurement for continuous soil monitoring.
The EC5 Soil Moisture Sensor is a low cost sensor that measures the dielectric permittivity of a surrounding medium using capacitance technology. The sensor uses a 70 MHz frequency, which minimises salinity and textural effects, making it an ideal sensor in agricultural and standard scientific projects. The EC-5 has a small area of influence. The sensor is 5cm in length and can measure a small volume of soil, ideal in situations such as glasshouse pots or localised areas of soil moisture (for example, soil for small herbs).
Lowest Cost Individual Sensors for Large Sensor Networks
Looking for a basic, no-frills soil moisture sensor? Look no further than the EC-5, a sensor that accurately measures water content in any soil or soilless media with minimal salinity and textural effects.
The EC-5 delivers research-grade accuracy at a price that makes large sensor networks economically practical. You can adequately characterise your site with sensors at multiple depths and locations, even if you’re on a tight budget.
Engineered for Accuracy
The EC-5 determines volumetric water content (VWC) by measuring the dielectric constant of the media using capacitance/frequency domain technology. Its 70 MHz frequency minimises salinity and textural effects, making this sensor accurate in almost any soil or soilless media. Factory calibrations are included for mineral soils, potting soils, rockwool, and perlite.
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´s robust design makes it easy to push directly into undisturbed soil to ensure good accuracy.
Reasons to pick the EC-5:
The AD-NODE is designed for those requiring precision in their analogue and digital measurements. With a 24-bit ADC, the AD-NODE supports two RTDs, a 0–10V with compressing range and a 4–20mA input. Each of the four dry-contact digital inputs is capable of simultaneously sampling at 1 kHz, with periodic reporting. Settings on the device can be altered remotely via LoRaWAN™ or locally via USB.
The METER Group (previously Decagon Devices) EC-5 has a small area of influence. The sensor is 5cm in length and can measure a small volume of soil, ideal in situations such as glasshouse pots or localised areas of soil moisture (for example, soil for small herbs).
