SECURUS/Hardware/Soil moisture sensor

Soil moisture sensors for trees and green spaces

Soil sensors measure conditions at a defined point in the ground. SECURUS shows histories and reports agreed thresholds, giving grounds teams additional information for assessing watering needs and routes.

Datasheet from the manufacturer

Technical data according to the manufacturer's datasheet, battery life under the stated conditions. All devices shown transmit via LoRaWAN. In addition to these examples, we also use LoRaWAN devices from other manufacturers depending on requirements.

Position the soil probe in the root zone

Soil type, depth and planting affect interpretation. Place the probe in the appropriate root zone and compare trends after rainfall and watering. Soil moisture monitoring should use representative locations.

FAQ

Sensor selection questions

Does one sensor measure the needs of an entire park?

It measures only its location. Different soils or planting may need separate points.
