Design and Implementation of Real-Time Reading System of Atmospheric Corrosion Sensor on Metal Material Using Internet of Things (IoT) Technology

Corrosion is an event of destruction of metal materials due to a chemical reaction between metal with substances in its environment. This research aims to develop a system that able to read the corrosion values from the existing atmospheric corrosion sensor and used internet of things (IoT) technology concept. The reading of sensor value conducted by connecting the atmospheric corrosion sensors with the IoT system, this IoT system will measure the incoming voltage value. Prototyping method was used for system development, that each stage was communication, quick plan and modeling quick design, construction of prototype, and deployment delivery and feedback. Several sensor, controller, actuator, and system used is arduino mega 2560 as the controller, k-type thermocouple sensor, DC voltage sensor, ESP9266-01, LCD 20x4, MySQL server, and wireshark as an apps for data transmission analysis. From the results of the research that has been done, the system can read and sent the data from atmospheric corrosion sensors to the private cloud and store the data on web server in real-time.
