How to avoid a frosty reception: wireless temperature sensors for fridge/freezer temperature control

When you store your food in your fridge, you expect it to last a fair bit longer than if you left it out in the open. We rely heavily on refrigerators to keep our food fresh. In fact, it was the invention of the refrigerator that largely gave rise to the way we shop for our groceries today. Back in the days before fridges and freezers, we were used to visiting small local shops on a daily basis to buy our meals for the day. Nowadays, we’ll go shopping once or twice a week and expect our food to last over that time period.

But what if our fridges and freezers failed? In a home, the worst –case scenario will be a week’s worth of ruined dinners. However, if the fridge or freezer happens to belong a restaurant or other catering business, the potential costs to the business could be critical.

The potential costs of a faulty fridge/freezer

From wasted food to lost business from downtime needed to replace the fridge or freezer, there’s a lot more at stake for a business.

Furthermore, restaurants have to keep their stock within tight temperature controls as a legal requirements. If they fall outside of these thresholds, well, they could risk fines and severe reputational damage. That doesn’t even account for any food poisoning that could occur because of a faulty appliance. Many restaurants also have to keep logs of fridge and freezer temperature, ready to show authorities when requested.

Controlling and monitoring the temperature of a fridge or freezer is, therefore, a top priority for many restaurants. However, many devices currently available aren’t that efficient or cost-effective. Luckily for today’s restaurant owners, there is a much simpler alternative: wireless temperature sensors.

How wireless temperatures can help

Wireless temperature sensors accurately monitor temperatures within a physical location (in this case a fridge or freezer) using a thermistor. They are very small and energy-efficient devices that can be simply placed in a fridge or a freezer to provide constant temperature updates. Because of their size and energy-efficiency, they’ll hardly be noticed and don’t require that much maintenance.

Thanks to these clever little sensors, restaurant employees won’t have to manually check fridge and freezer temperatures regularly to ensure that perishable food remains fresh.

Wireless temperature sensors, like the ones that Wireless Sensors UK stock, are part of the Internet of Things (IoT). In simple terms, this means that they are part of a network of devices connected to the Internet and that allows them to do some really useful stuff – like constantly uploading and monitoring temperature data. If there is any fluctuation or failure in fridge/freezer temperature, thanks to the IoT-connected devices, a restaurant owner will know in mere minutes via an email, SMS or a dedicated app.

They say that big things come in small packages, and for wireless temperature sensors, this most certainly rings true. This unassuming piece of tech might not look like much but it is going to have a huge impact on the quality and freshness of perishable food. Thanks to the likes of Amazon Echo and Google Home, the world around us is getting ever-smarter. It’s time our fridges and freezers did too.
