Real-Time Tank Level Monitoring System using Modbus-MQTT and Web-Based Visualization

Abstrak

In this paper, the presented system to monitor the volume of diesel inside a tank using a pressure sensor. The system employs a Data Acquisition Unit module to collect analog data from the pressure sensor, which is submerged in the diesel tank. Sensor data is transmitted via RS485 communication to a DTU device that converts it into MQTT packets, The MQTT packets are sent to an MQTT broker, which acts as a bridge to a web or mobile app for real-time monitoring of the diesel tank's level. The results of the implemented system shows real time readings of liquid volume inside the tank from the pressure of the liquid via mobile and web app, also the data of the sensor is saved to local database for further analysis.
