Measurement system technology is increasing along with the development of digital technology. Likewise, the technology for measuring water pressure in pipes is made digitally, although many conventional measurements still exist, such as the flow meter in housing in general. The purpose of this research is to make a tool based on Internet of Things technology, especially water pressure sensors that are installed in various water sources to obtain data in real time to ensure sufficient pressure to push water to the customer. Each water pressure sensor node is monitored from the system dashboard in real time. In this paper, the author offers an IoT-based measurement system for microcontroller technology on a smart pressure meter using a water pressure sensor controlled by the NodeMCU and the pressure bar is calculated then the data is sent to the cloud with the GPRS module. The results will be displayed on the monitoring system dashboard in form of pressure data, volume in the water reservoir. The results of this study are the implementation of DWM IoT technology is able to monitor water pressure at several PDAM nodes by recording data and displaying pressure data in real time graphical form on the DWM IoT dashboard.
