Description
Sensor Hub Soil Monitoring is a solution that helps monitor critical soil parameters such as soil moisture, temperature, and electrical conductivity.
The sensor Is high quality and has stainless steel probes that have a long life when buried directly in the soil. It has built-in temperature compensation for accurate measurements.
Suitable for use in agriculture, irrigation, greenhouse, grass farming, water conservation, soil testing, and more.
Multiple soil monitoring sensors with different probes IO can be connected to a single sensor hub to vertically monitor parameters in different soil layers. The Splitter cable can connect several Sensor Probes and Probe IOs to a single Sensor Hub port. The distance between the Sensor Hub and Sensor Probe/Probe IO can be extended via the Extension cable.
Note: Sensor Hub with Sensor Probe IO and connected sensor cannot be powered on batteries. You need to use the included power supply only.
The Sensor Hub has two variants based on the communication type - LoRaWAN® only and LoRaWAN®+NB IoT. SensorHub's NB-IoT module supports two types of LTE (Long-Term Evolution) categories, namely CAT M1 and CAT NB2. CAT M1 offers higher data rates and lower latency, while CAT NB2 provides ultra-low power consumption and greater coverage, making it an ideal choice for devices that operate on batteries and require long-term connectivity.
