Conductivity sensing measures electrical conductivity (EC), how readily a liquid or soil conducts an electric current. Because conductivity rises as dissolved ions increase, it serves as a fast proxy for salinity, fertiliser concentration, and total dissolved solids, usually expressed in µS/cm or mS/cm and often paired with temperature compensation for accurate readings.
LoRaWAN conductivity devices place an EC probe in water or soil, sample on a set interval, and transmit the value in a compact payload over long-range, low-power radio. This lets a single gateway collect EC data from probes spread across fields, reservoirs, tanks, or remote outfalls without wiring or cellular coverage.
Typical deployments include:
- Agriculture, hydroponics, and irrigation nutrient management
- Surface and groundwater quality and saltwater-intrusion monitoring
- Aquaculture, wastewater, and industrial process water
When comparing devices, weigh measurement range and accuracy, probe and temperature-compensation method, enclosure or IP rating for submersion, battery life, supported regional frequency plans, and whether a ready-made payload codec is provided.

Frequently asked questions
What does a LoRaWAN conductivity sensor measure?
It measures electrical conductivity (EC), the ability of a solution or soil to conduct electric current. EC rises with dissolved ions, so it indicates salinity, nutrient load, or total dissolved solids, typically reported in µS/cm or mS/cm.
What is conductivity (EC) used for?
EC monitoring is common in water quality, hydroponics and agriculture (nutrient and salinity management), aquaculture, wastewater, and industrial process water. It helps detect contamination, dosing errors, and saltwater intrusion remotely.
How do I choose a LoRaWAN conductivity sensor?
Compare measurement range and accuracy, probe type and temperature compensation, ingress protection (IP rating) for submersion, battery life, supported regional frequency plans, and whether a payload codec is provided for your network server.
