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 ...

A low-cost (~$100), do-it-yourself (DIY) ultrasonic water level sensor/datalogger has been designed, constructed, and tested for use in education, citizen/community science, and research settings. The ...

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 ...

This project is a smart water level controller built using Arduino UNO, an ultrasonic sensor, and EEPROM for memory storage. The system automatically monitors the water level in a tank and controls ...

My water level maintenance consists of dropping a garden hose in the pool and letting it run for 30 minutes; I have to do this less than once a month. But like I said, it's a cool project.
