Choosing the Right Soil Moisture Sensors for Your Greenhouse

Not all soil moisture sensors are equal. Here is what to look for when automating irrigation in containers, beds, and commercial zones.

Soil moisture sensors turn guesswork into actionable data—but only when they are installed and calibrated correctly.

Match the sensor to the media

Container mixes, coco coir, and field soil all behave differently. Choose sensors rated for your substrate and expected moisture range.

Placement matters

Install sensors where roots are actively feeding, not at the driest edge of a bench. For mixed crops, dedicate sensors per zone instead of sharing one reading across unlike plants.

Set thresholds with intent

Trigger irrigation when moisture drops below a target, but include a minimum interval so the system does not short-cycle during fluctuating conditions.

Grobotics makes it easy to enable or disable moisture-driven rules per zone, so you can experiment without disrupting the entire operation.
