Arm Based Liquid Level Detection and Fluid Control System

Abstract - Efficient liquid level detection and fluid control are crucial in various industrial and domestic applications, such as chemical processing, water management, and biomedical systems. This project presents an ARM-based liquid level detection and fluid control system using an STM32F1 03C8T6 microcontroller, designed for precise and automated fluid regulation.The system consists of two beakers, one for liquid level detection and the other for fluid flow regulation. Ultrasonic sensor continuously monitor the liquid level in the detection beaker. If the liquid level falls below a predefined threshold, the STM32F103C8T6 microcontroller activates a control mechanism to regulate the fluid flow from the second beaker to restore the desired level. The control algorithm ensures real-time adjustments, minimizing overshoot and preventing spillage.This ARM-based liquid level control system finds applications in industries requiring precise fluid handling, such as pharmaceuticals, food processing, and wastewater treatment. Future enhancements may include wireless monitoring, adaptive thresholding, and machine learning-based predictive control for further optimization Key Words: STM32F103C8T6, Liquid Level Detection, Fluid Control System, Water Level Measurement ,Calibration Algorithm, Data Processing, Real-time Monitoring, Variable Power Supply, STM32CubeIDE / Keil / Arduino IDE, C/C++ for Embedded Systems, PWM Control.
