Temperature cables are also used as input in aeration fan control, ensuring that the fan is operated only when the ambient air is cooler than the grain, for efficient cooling with minimum fan operation and without heating the grain.
Tracking grain moisture levels during drying ensures that the fan is operated unless the grain is thoroughly dried. It also helps to prevent over-drying the grain, estimating the safe storage period and potential risk of spoilage, and making the right management decisions about handling, storing and selling the grain.
