The Implementation of Aichi OF05ZAT Sensor on Water Flow and Volume Based on NodeMCU

Abstract

The development of clean water storage systems often faces challenges in monitoring water usage when the reservoir is not equipped with a measurement system. This study presents the design and implementation of an Internet of Things (IoT)-based monitoring system for water flow rate and volume using the Aichi OF05ZAT sensor and NodeMCU microcontroller. The system integrates an ultrasonic sensor (HC-SR04), Aichi OF05ZAT flowrate sensor, solenoid valve, relay, and water pump, with software developed on the Arduino IDE platform utilizing IF–ELSE commands, interrupts, and millis() functions. Data acquisition and monitoring are conducted through the Blynk mobile application. Experimental results show that the system can effectively and automatically measure reservoir water levels from 2 cm to 32 cm, with an uncertainty of ±0.053%, and transmit real-time data to the Blynk app with a 1-second delay. This implementation demonstrates a reliable and efficient approach for continuous monitoring and management of water reservoir systems..
