Losing sleep wondering if you’re freezer is secretly thawing valuable frozen foodstuffs? Worry of secretly spoiled steaks no more –
William Grill wanted to make sure his freezer didnâ€™t cut out and ruin his frozen food. He was concerned that when he traveled, his food could defrost and re-freeze â€” thus compromising his frozen steaks â€” without his knowledge. So, he developed a gadget that measures freezer temperatures, keeps a history of variance and sends an alarm if freezer temperatures rise above a set range. The gadget is built around a small controller, an alarm and a temperature sensor. While temperature monitors are common, Grillâ€™s device remembers temperature variance and displays the length of time the freezer rises above the set temp. The gadget is relatively small and costs less than a couple of steaks bought on sale and stored in the freezer.
