Title: smart automatic open and close window
Inventor: SEO DONG HA
IPC: E05F15/77
Filed: 2018-12-18
Abstract: Windows are normally opened and closed to facilitate humidity and ventilation control. Meanwhile, busy modern people usually spend their time outside more than at home. The present invention has been invented for people who are physically disabled or do not normally stay at home to use a smart window connected to the Internet instead of manually opening a window. A temperature sensor, a humidity sensor and an air sensor installed in an air purifier are connected in a house. Through such sensors, a total score is calculated based on information such as temperature, humidity and the like in the house. If the score is more than a predetermined score, a smart window provides a signal to open the window. The abovementioned sensors are connected with the smart window, and the smart window is connected to the Internet to continuously update the weather of the current region, thereby checking weather information. A motor for opening or closing the window on a hardware basis is installed on the window. The motor is operated if the digital signal is 1 and cannot be operated if the signal is zero through 3-state buffer by receiving the signal transmitted from the smart window. According to characteristics of the 3-state buffer, a current can flow only when an enable port is 1, whereas the current cannot flow if the enable port is zero. Thus, since a voltage cannot be applied unless the smart window transmits a signal, electricity can be saved, which is a positive part.
