Smart Water Level Monitoring and Automatic Pump Controller Using Arduino Uno and Ultrasonic Sensing: Design and Simulation
Year: 2026
Type: preprint
Abstract: Manual monitoring of water storage tanks can lead to overflow, dry running of pumps, water wastage and unnecessary energy consumption. This paper presents the design and simulation of a low-cost, standalone water-level monitoring and automatic pump controller based on an Arduino Uno and an HC-SR04 ultrasonic sensor. The controller converts the measured distance between the sensor and the water surface into a water-level percentage and applies a two-threshold hysteresis strategy. The design was verified using the Wokwi simulator. A single-layer PCB layout and enclosure design were also developed. The results are simulation-based, and physical tank testing is identified as future work.
