Monitoring Soil Parameters with iNut: Real-Time Soil Moisture, Temperature, pH, EC & NPK

Soil doesn't speak in words, but it always "tells" its state through numbers: soil moisture shows whether a plant is thirsty or waterlogged, pH determines whether the plant can absorb nutrients, EC reflects the salt/fertilizer concentration in the soil solution, and NPK reports the remaining nitrogen – phosphorus – potassium. Manual measurement is sporadic — a few readings a week — arriving late and insufficient for timely decisions: by the time you see yellowing leaves, rotting roots or compacted soil, it's usually too late.

iNut turns "reading the soil's pulse" into a continuous data stream. Dedicated sensors placed at the root zone take readings every few minutes; data is transmitted wirelessly to the gateway, compared against thresholds to auto-irrigate and auto-fertilize, push instant alerts and display visually on the dashboard. Growers no longer have to guess — they see the soil.

A single iNut probe inserted into the root zone can simultaneously read soil moisture (VWC – the water actually available to plants), soil temperature (affecting germination and root activity), pH (nutrient solubility & uptake), EC (salt/fertilizer concentration, warning of salinity or over-fertilization) and NPK (nitrogen – phosphorus – potassium). Everything arrives in one place every few minutes — dense enough to reveal trends, not just a single snapshot.

Fields, riverbanks or hillsides often have no grid power and running cables is a hassle. iNut RS485 reads the sensors and relays the data over WiFi Mesh — nodes pass signals to each other, covering long distances without extra infrastructure, powered by solar panels so a single install runs all year round. Multiple measurement points spread across the plot all feed into one gateway.

Once you have the data, let the system act on it. Set thresholds once: soil moisture drops below the limit → irrigation valve opens automatically, and shuts off once moist enough; low EC signals nutrient deficiency → dosing pump injects the right amount of NPK then stops; pH drifts off range → an alert is raised for action. The logic runs at the edge layer on iNut PC, or controls relays/valves via iNut Muro — closing the loop between measurement & adjustment right on the field.

Soil suddenly turning saline, moisture plunging from a burst pipe, or pH drifting outside the safe range — you need to know right away, not the next morning when you walk out to the field. iNut PC at the edge continuously compares readings against thresholds and pushes alerts via Email/Telegram the moment limits are breached, with a 4G uplink so it keeps working even where there's no fixed internet. One timely message can save an entire crop.

All soil data is displayed visually on iNut Platform (self-hosted cloud, SCADA-style dashboard): moisture/temperature/pH/EC charts over time, a map of measurement points, thresholds and alert history. iNut Datalogger records every minute for retrieval and trend analysis, while the iNut app lets you view readings, change thresholds and remotely switch devices on/off right from your phone. Want to connect to an existing SCADA/PLC? iNut OPC speaks OPC UA/Modbus/XML-DA.

From riverside monitoring stations to control cabinets out in the field, iNut devices are built to withstand sun and rain: sealed enclosures, solar power, wireless transmission and automatic reconnection. No one needs to be on standby, no grid power required — growers simply open the app to see how the soil is doing.
