A tiny weather forecast device
Some office buildings in Japan have a weather forecast device. It is so tiny you may find it adorable. This device is useful when you are unsure whether it will rain or not and you do not want to carry an umbrella in vain. That is unpleasant, and you might end up losing it somewhere.
This weather forecast can be found in elevators. The umbrella sign lights up whenever it is raining so that people who have to leave the office will know what is going on outdoors. Some developments in technology are just stunning and make our lives easier!
