5.2 Sensors and predictive maintenance
IoT sensors (Internet of Things) collect data on temperature and humidity and send alerts if thresholds are breached. This forms part of a closed-loop control system.
Instead of waiting for refrigeration equipment to fail, the data can be used for predictive maintenance, where the system warns of an impending breakdown before it occurs.
An example from an Icelandic kitchen´s shows that such a system reduced refrigerator breakdowns by 30% over a three-month period.
