Glossary

Aeration

Moving outside air through a bin of grain to change its temperature, and to a lesser extent its moisture, toward a target. Distinct from drying, which removes substantial moisture using heated air.

Chester X1

GrainLink’s flagship grain monitoring controller. One per bin.

EMC (Equilibrium Moisture Content)

The moisture content that grain will eventually reach if exposed to air at a given temperature and relative humidity, given enough time. GrainLink’s fan algorithm uses EMC to decide whether running the fan would dry, wet, or leave the grain unchanged.

Heatmap

A cross-section visualization of a bin showing each sensor’s temperature reading on a color gradient, with cool sensors blue and warm sensors red. The fastest way to spot a developing hot spot.

Hot spot

A localized region within stored grain where temperature is rising faster than surroundings. Usually the first sign of biological activity (mould, insects, or self-heating).

Location

A physical site (yard) in the GrainLink dashboard. Holds one or more bins.

OTA update

Over-the-air firmware update. Pushed automatically over cellular; no action needed from the user.

Sensor cable

The vertical cable suspended in a bin that carries multiple temperature (and optionally humidity) sensors at different heights.

Spoilage

Loss of grain quality or quantity due to mould, insects, or self-heating. The condition GrainLink exists to prevent.
