It's always handy to know the temperature, if only to let those at home know how much you're enjoying the nice weather. But the E-Temperature module has even more advantages. For example, you can use it to measure the exact temperature in the fridge to ensure that your food and drinks or medicines stay properly chilled. The E-Temperature module also displays the humidity, which is useful for preventing mold growth in the shower, for example. The E-Temperature module warns you if the temperature exceeds or falls below the temperature you have set.
