Abstract

In this study, a dependable liquid level monitoring and control system for automated home or industrial settings is presented. The system uses state of the art Internet of Things (IoT) technology to accomplish its goals. The suggested system, which consists of a minimum of four interconnected functional units, utilises Wi-Fi connectivity to establish communication between the parts. These nodes can efficiently share data by using the simple MQTT protocol, which enables scalability by allowing the installation of additional nodes to manage various tank and reservoir levels. In the suggested approach, the Sensor node simultaneously subscribes to several topics pertaining to user settings and measurement frequency while publishing measurements to the server. By subscribing to these topics, the Actuator Control node may control pumps or valves appropriately and communicate their current states. The User Interface node publishes changes to user configuration and subscribes to all topics from other nodes. All firmware codes were created using the C++ libraries and programming structures in the Arduino development environment. An Android application that has been specially created can serve as the system's graphical user interface, allowing users to interact with it via a variety of portable devices.
