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 instance, you can use it to measure the exact temperature in your refrigerator to make sure your food and drinks or medications stay properly chilled. In addition, the E-Temperature module displays the humidity of the air, which is useful for preventing mold, for example in the shower. The E-Temperature- module warns you when the temperatures you ve set are exceeded or undercut.
