In the pipe there is a valve to control the flow of water from one tank to another. So someone has to go to the valve and turn it if they want to stop or start the water flow manually, which will take time and energy. So it has the potential to increase human error when the valve rotation is too late or too fast. Therefore, an IoT-based tank system was developed which can simplify and speed up controlling the water level in the tank. In this system, a pressure sensor is used to read the water level in the tank and a servo valve to regulate the water level is connected to the Omron PLC I/O module. HMI NB10W-TW01B and PLC are connected to form an interface that can monitor and control the water level in the tank. PLC will be used for the PID control system.otherPLCPIDSystem ControlHMIIoTInternet of ThingsTECHNOLOGY::Electrical engineeringelectronics and photonics::Electrical engineeringelectronics and photonics::Other electrical engineeringelectronics and photonicselectronics and photonics::Electronic measurement and instrumentationTECHNOLOGY::Information technology::Systems engineeringBook32322110561008128001KODEPRODI30402#Teknik Instrumentasi
