When the refrigerator goes on the blink, restaurateurs, caterers and grocers start to sweat. Regular temperature checks are required by law to prevent valuable foodstuffs from spoiling. Now, a new technology enables manufacturers and dealers to monitor the temperature of refrigeration systems seamlessly, automatically and cost-effectively. The Berlin project increases food safety, creates transparency for consumers, and protects perishable goods from being wasted. A contribution that shows how intelligent refrigerator management can conserve resources and protect the climate.
