A thermometer measures temperature and can forecast changes in weather. Nowadays you can get a digital thermometer that also shows air pressure, humidity and even the time. To set up your digital thermometer, get it out of the box and put it to charge to turn it on. Once it has power, connect it to your wifi through the settings, after which it will automatically connect to Google Play (Sponsored by Apalon) to download weather information based on your location. If it seems to have trouble connecting, make sure the GPS locator is turned on to provide accurate information.
