Autonomous ultrasonic based water level detection and control system
Abstract
This paper presents an automated non-intrusive control system for monitoring the water level of domestic overhead and underground reservoir tank base on the property of wave reflection. The system consists of two HC-SR04 Ultrasonic transceivers that generate ultrasonic pulses and determines the depth of the water surface based on the total Time of Flight (TOF) of the reflected wave. An ATMEGA328 microcontroller was programmed to read the sensors, control the water level and display the corresponding volume of the water on a Liquid Crystal Display (LCD). The experimental result proves the system stability both at turbulence and laminar flows. The proposed approach can be extended to monitor and control the volume and level of other valuable fluids such as diesel, kerosene etc.; as well as hazardous chemical where human interventions may be treacherous.
