The rapid evolution in the field of electronic technologies, such as embedded technology, computer communication and network technology, microelectronics and sensor technologies, AI and machine learning, virtual instrumentation, and VLSI technologies, among others, enabled the vast proliferation of the field of electronic instrumentation. Due to this, the field of smart electronic systems is emerging in the fields of industry, automation, chemistry, medicine, and agriculture. Nowadays, integrating virtual instrumentation with sophisticated microcontrollers provides a suitable solution to meet the demand for advanced, smart instruments that simplify use and reduce design time across various applications. Therefore, this paper presents the design and implementation of an automated liquid level control system with the help of LabVIEW and Arduino. The present system is designed to maintain the liquid level in a tank at a desired level by automatically controlling a pump or valve based on real-time measurements obtained from an ultrasonic sensor or IR. The primary goal of the system is to provide a low-cost, efficient, and user-friendly solution for liquid level control in industrial applications. The system employs Arduino for data acquisition and control, while LabVIEW provides a graphical interface for monitoring and interacting with the system. This work demonstrates the feasibility of integrating hardware and software tools to automate and monitor liquid levels in real-time.
