This experiment can be divided into two parts: hardware and software. Hardware implementation can also be divided into four parts which will be used harmoniously with each other : Arduino control module, Load-Cell with HX711 weight sensing module, ESP8266 wireless network transmission module and mobile devices. The software will first use MIT App Inventor 2 to design the mobile device App interface and functions, then will use JavaScript and HTML to design and write webpages and use PHP and MySQL as a back-end platform – setting up dynamic web pages that can display use a real-time data Platform, and use web pages or mobile device apps to deliver relevant notifications or alerts to achieve a preventive diagnostic system that combines the Internet of Things.工業4.0物聯網無線感測網路行動裝置Industry 4.0Internet of ThingsWireless sensor networkMobile App
