The Internet of Things on the Farm: A Network of Sensors Making Better Decisions | Agricultural Technology - Akhdar

The idea and why it matters

The Internet of Things connects sensors to a single communication gateway and monitoring panel.

The real value lies not in the number of devices, but in measuring a variable that influences decision-making, within a representative field location, and at a time interval that matches its rate of change.

practical application

Start with a trial area and a root-depth moisture sensor, along with a temperature and humidity station.

Calibrate the readings with a manual soil sample, establish the alarm threshold, and then connect it to an irrigation valve after a full season of testing before transitioning to automatic operation.

What should be measured?

Track the percentage of missed readings, the difference between the measurement and manual inspection, the amount of water per kilogram of crop, and the number of alerts that led to useful action. A good dashboard shows a time trend and doesn't just show a momentary number.

Mistakes and risks to avoid

The most common mistakes are placing the sensor too close to the dripper, neglecting calibration, relying on an unstable connection, or automating irrigation before understanding the soil.

A manual operating mode and a plan for when the power or grid fails are essential.

Actionable summary

A practical guide to building a sensor network that measures soil moisture, temperature, and salinity, and translates the data into actionable irrigation and fertilization decisions.

Start small, establish a baseline, and then scale up the solution after measuring the results and reviewing the costs and risks.
