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.

Haya and Taha built a water level sensor. Watching their video (you’ll need to crank the volume) it dawns on us all of the great things that are learned in a project like this.

8: Arduino Water Level Indicator 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 ...

I've got an Arduino/Bluetooth (Bluetooth Bee-Standalone). I've hooked it up with an HC-SR04, it's intended to be mounted at the top of a rain barrel to measure the water depth.

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 system has an Arduino commanding an irrigation system based around a pump delivering water from a reservoir. It’s paired with a water level sensor to keep an eye on the water available to ...

LEDs on the Arduino can be programmed to indicate if the sensor is or isn’t immersed by the liquid to determine liquid levels. The devices are compact, allowing them to be deployed within constrained ...

As the top sensor goes low (water above level C), the CLR signal is activated and the output of the flipflop is low. This allows Q1 to turn on and activate a triac or relay for the pump.
