Power is crucial for the factory to ensure no product The estimated wastage incurred per freezer is around
wastage due to a power failure and the protection of $3,000 per incident. Thus, it is possible to reduce
equipment. The company has about 230 freezers (see wastage by installing IoT power surge detection devices
Table 9). to alert the company supervisor when a power outage
occurs.
