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 demonstrates a water level monitoring system using an ultrasonic sensor and an Arduino. The system measures the water level in a container based on input voltage and displays the height ...

“Part Fill” Valve? Yes, Part Fill valves are widely used in Rainwater tanks. The valve will open once the water level in the tank has fallen to a low position, this allows the town mains water to ...

In Texas — at least around Houston — we don’t have basements. We do, however, have bilges. Both of these are subject to taking on water when no one is paying attention. A friend of mine asked me what ...
