A web management sensing and control system built on Arduino MCUs and Linux server was successfully developed. The server monitors all peripheral devices through RS-485 interface which was based on Modbus protocol. The terminal devices used in this study were Arduino module, series-to-parallel module, temperature and humidity sensing module, air pressure sensing module, RFID reader, voice module and industrial standard PID controller. High security Linux system with web and database server was used in this study. The server collects and analyzes all data from peripheral devices and provides a well-use interface.
