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 ...

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 ...

📌 Description The sensor is placed at the top of the water tank. It sends out an ultrasonic pulse and measures the time taken for the echo to return from the water surface. The code then calculates ...

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 ...

The Arduino Plant Watering System is designed to automatically supply water to your plant's soil once its moisture level falls below a particular point. The system relies on two key components to ...
