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 ...

Water level measurement is performed using ultrasonic sensors - HC-SR04, or its waterproof variant JSN-SR04T, other sensors with Trigger / Echo signals from US-02X, IOE-SR0X, HC-SR0X, HY-SRF0X, ...

Automated Water Level Controller Abstract: Developing an automated water level controller system utilizing Arduino, ultrasonic sensor, and MOSFET to maintain a consistent water level in a main tank by ...

Here is a tested Arduino project that uses 3 sensor probes as water level indicator with 3 leds and one LCD display + a simple controller that turns on a motor when the water has reached the desired ...

The water level indicator project utilizes an Arduino Uno microcontroller, an LCD display, and a Bluetooth module to provide an efficient solution for monitoring water levels and controlling a motor.

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

But like I said, it's a cool project. I've thought about building an ultrasonic water level sensor, connected to an ESP32 or Pi Zero to report water levels to... something TBD.
