This project demonstrates an Automatic Water Level Controller using an Arduino Uno, HC-SR04 ultrasonic sensor, a relay module, and two push buttons. The ultrasonic sensor measures the distance from ...

The basic design idea is to set two ports of the MCU for water level detection, one port for automatic/manual mode switch selection, and two ports for visual status indication. From the reading of the ...

Setup and Components Water Level Sensor: Connected in a voltage divider configuration with a fixed resistor (10kΩ). The junction of the sensor and the resistor is connected to an analog input pin (A0) ...

Water tank overflow is a common issue that results in a significant amount of water wastage. While there are several solutions available, such as the installation of ball valves that automatically ...

Introduction Although the idea of a smart, active water tank is more complex and costlier than its passive counterpart, the active type has clear advantages in terms of energy economy and water ...
