How does the sensor work?
Soil moisture is measured based on a proprietary and patent-pending algorithm that combines impedance and resistance properties of the soil. Data is sent by LoRaWAN from the probe to the gateway. With the 2G/3G/4G cellular connectivity, the data is sent from the gateway to a server owned by the provider, and through the cloud to the Sensoterra server.

What is the range of a sensor?
The guaranteed range from probe to gateway is 4 kilometers line of sight. Please be aware that obstacles between probe and gateway may decrease the range, and optimal conditions will increase the range.
What is the lifetime of a sensor?
The energy consumption is extremely low, allowing for years of operation. Batteries don’t need changing. The probe is watertight for rain and irrigation (IP67), and can even be buried or submerged, depending the strength of the LoRaWAN network strength. All Sensoterra probes have a lifetime of 6-8 years with hourly measurements (under normal operation).
What is the warranty of a sensor?
All Sensoterra sensors have a 3 year production warranty and lifetime warranty on the stainless steel measurement pins.
Can I change the battery of the sensor?
Our sensors are farm tough, 100% maintenance free and hammerable. To achieve this the sensors have a non-replaceable, built-in battery which lasts 6-8 years with hourly measurements (under normal operating conditions). At the end of the lifetime of a sensor, it can be returned to Sensoterra for responsible refurbishment and recycling.
