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 ...

To supply targeting data for the launcher, an Arduino Uno uses an ultrasonic sensor pair mounted atop a servo. As the servo rotates, the returns from the ultrasonic sensor are plotted on a screen ...

Accurate flow measurement is an essential step both in the terms of qualitative and economic points of view. Flow meters have proven excellent devices for measuring water flow, and now it is very easy ...

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 ...

It also has a GSM/3G modem, allowing it to report the measured water quality to a central database. All of this is housed in a 3D-printed enclosure that makes the whole setup easy to carry and ...

If you're looking for ways to use less water, Instructables user tamberg developed a DIY water faucet sensor that shows you when you've used up a liter. Using an Arduino, flow sensor, and colored ...
