I remember the day vividly. I had just returned from a long vacation, and as I opened my freezer, I was met with a foul smell. All my frozen goods had thawed, and my refrigerator was no longer cooling. Everything had gone bad. Did I mention the foul smell?
Of course, I had no idea how long the darn thing hadn’t been working. But one thing was sure: I didn’t want to let something like this happen again. But what could I do, apart from breaking the bank on some new fancy smart refrigerator? Then I remembered that time I was researching a story about vaccines and how the so-called “cold chain” logistics involved sensors that immediately alert staff that a batch is in danger of getting spoiled. Lo and behold, the same type of sensor can be used on your fridge nowadays.
That’s what eventually set me on a journey that saw me try over a dozen wireless temperature alarm monitors. First, I’ll leave you with my top five picks and then I’ll share with you some tips on what to look for in a good temperature alarm monitor.
