This probe measures the water content of the soil at one depth: the one where your roots are working. Eight times a day, the value comes up to the platform as a volumetric water percentage — a figure directly comparable from one week to the next when deciding on an irrigation round. Below your threshold, the sensor does not settle for a graph: it phones you.
How it works
At its core is an HSTI capacitive probe, buried at the rooting depth of the crop. It arrives pre-calibrated for 3 soil types: you pick yours in the interface, nothing else. Transmission goes directly over the multi-network GSM network thanks to the included SIM card — no gateway, no box, no antenna to install. The IP66 housing stays outdoors all year round, in open fields as well as under a greenhouse or agrivoltaic panels.
No subscription, in practice
You receive the sensor preloaded: 350 Mo of data, 60 calls and SMS, unlimited email alerts, platform included. Depending on your settings, this plan and the battery last 3 to 5 years. When they run out, you replace the battery and top up the SIM — a one-off expense, not a monthly rent. In between, the sensor works on its own and you keep control of your thresholds, your alert numbers and your reading history.
Frequently asked questions
Do I need to calibrate the probe for my soil?
No. It arrives pre-calibrated for 3 soil types: you simply select yours in the interface, and the reading in volumetric water percentage is directly usable.
How am I alerted in case of water stress?
You set your thresholds on the platform. When they are crossed, the sensor automatically calls up to 10 phone numbers, with SMS and unlimited email on top.
What happens after the 3 to 5 years?
You replace the battery and top up the SIM card plan. It is not a subscription: in the meantime there is nothing to pay, and the platform remains included.
At what depth should the probe be installed?
At the rooting depth of your crop. Once buried and switched on, it transmits its readings 8 times a day, with no further intervention.
