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 ...

I wanted to know when my rainwater well is empty and I've read about solutions using ultrasonic sound measurements. So I decided to create something like that for my rainwater well. I chose an ESP32 ...

This project is a real-time dam water level monitoring and alert system designed to enhance safety, efficiency, and sustainability in water resource management. It is built using an Arduino Uno, an HC ...

We are currently in the process of putting in a backyard pool. This is an in-ground gunite pool. I inquired about an auto-fill system from the pool builder but he talked me out of it. He explained ...

Tilt sensors are essential components in security alarm systems today. Standalone tilt sensors sense tilt angle or movement. Tilt sensors can be implemented using mercury and roller ball technology, ...

Abstract: We connected $\mathbf{p H}$ sensor and solar cell into Arduino Board to control data transmission via red laser communication or popular known as visible light communication (VLC). The ...
