Abstract

Supervisory data and control aquation (SCADA) technology is generally applied to large industrial solid technology used for automation and control. Generally, this technology is closed to only one specific system, but with the advancement of open-source microcontroller technology and the internet that exists today, SCADA technology can be built with microcontrollers and node-red as a tool based on opensource web-based programming that can be used to connect hardware and software with Modbus protocol. This research uses an STM32 microcontroller as a sensor interface, and actuator with communication through RS-485 serial. The STM32 microcontroller is a low-cost single chip that has the ability to communicate via serial communication lines with personal computers or other devices that have the same serial communication lines, STM32 can also be programmed with the Arduino IDE which is open-source. The HMI interface is visually built using Node-red so that it can give commands and read data from sensors. The conclusion of this research is that the SCADA system can be built with STM32 microcontroller with MODBUS protocol and an open-source web.
