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 will cause the sensor switch to mal-function. Meanwhile, since there are no means to detect the water level of the basement water tank, it is possible that the pumping motor will be burned if ...

I've just come across a no-name non-contact, high-precision 80 GHz mmWave radar sensor for liquid level detection with a 40m ...

It is a modular design with an Arduino Mega and a lot of I/O for a serious fish tank. There are controls for heaters, fans, lights, wave makers and even top-off valves.

LVDTs sometimes work better than pressure sensors for gauging tank volumes. A common way of measuring the level of liquid in a tank places a low-pressure sensor at the bottom. The pressure readout ...

To monitor these levels, RV manufacturers include tank-monitoring systems. These systems generally consist of probes placed at 1/3-tank-level intervals.

Because of the affordability and seeming ubiquity of the Arduino platform, they have been hard at work this last month trying to get their Geiger counter sensor board for an Arduino out the door.
