Recently, a company has developed a smart umbrella, which can not only open and close automatically, but also automatically adjust the angle of the umbrella surface according to the weather conditions. This smart umbrella has built-in multiple sensors, which can sense information such as rainwater density and wind force, so as to automatically control the opening and closing of the umbrella surface. In addition, this smart umbrella is also equipped with a smart phone APP, through which users can control the opening and closing of the umbrella and adjust the angle, and can also view information such as weather forecasts and umbrella usage records. The design of this smart umbrella provides a more convenient and smart choice for people to travel.
