A Novel IoT System for Diesel Level Monitoring

There is a need to monitor the fuel level in diesel generator systems to ensure an uninterrupted power supply. Recent techniques such as ultrasonic sensors and float-based systems have faced challenges including high costs, mechanical wear, and limited accuracy in varying environmental conditions. Additionally, integrating these systems with real-time communication networks and mobile interfaces presents significant difficulties. This research study proposes a novel IoT system to monitor diesel levels in a diesel generator tank. The proposed work focuses on developing a wireless diesel tank monitoring system utilizing the WebSocket protocol for real-time communication between fuel sensors and a mobile app in remote locations. The mobile app, accessible via Wi-Fi networks, offers a simple interface for users to log in, view current diesel levels of different tanks, and access consumption statistics. Diesel levels are presented as a percentage, converted from voltage measurements. The system sends notifications if levels fall below predetermined thresholds. One challenge faced in this system is the need to cut the length of the sensor to fit the tank, which affects the sensor's accuracy. Despite this, the integration of the capacitive fuel level sensor, ESP8266 microcontroller, and WebSocket communication enables a seamless and robust solution for diesel level monitoring. A potential divider circuit was used for mapping the sensor output to the on-chip ADC of the ESP8266 microcontroller. This efficient and user-friendly solution aims to optimize diesel usage and facilitate timely refills in remote areas. This paper contributes to the field of remote monitoring systems by offering a practical and scalable solution for diesel level monitoring in diverse applications.
