Automation System of Water Treatment Plant using Raspberry Pi.3 Model B+ Based on Internet of Things (IoT)

The application of the internet of things technology in the automation system of water treatment plants can be applied in various countries. In the previous system, they used an automatic system using Programmable Logic Controller (PLC) and still monitored manually. This previous system could not be monitored and controlled through internet access. This paper focuses on developing an automation system for the disposal of existing sludge in the sedimentation plant on Water Treatment Plant (WTP) using the Raspberry Pi and adafruit.io cloud server as the MQTT server. In this proposed system, Raspberry Pi has a function to facilitate the computational process and communication connection to the internet network. The adafruit.io MQTT cloud server is used as a receiving broker to publish sensor values and actuator status from Raspberry Pi which can be accessed by the client.
