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'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. What's the best ...

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 ...

Conceptually this seems easy, but I need to find a sensor that can tell me the water level (or the delta from filled) and report that data out via wifi. Anybody know of something that would work?

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 first is an LED matrix that eleven-year-old Daniyal brought to life using Arduino. In the video, he displays each letter of his name on the 8×8 red LED module and then shows his version of ...

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 ...
