This project is a collaboration with the Department of Architecture, National Cheng Kung University. When the data collection reaches 12 bytes, it will use the IoT transmission protocol (sigfox module) to send it to the database, and display it through the web and mobile APP, giving the user a visual presentation and real-time warning. I am responsible for is the modular appearance concept design and data testing. The appearance refers to the design of the louver to increase the air intake to reduce the heat accumulation of the sensor, and the white 3D printing wire to avoid absorbing solar radiation. In addition, the sensor model Assemble, reduce the trouble of installing and replacing the sensor through the modular design.
