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 ...

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

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 ...

His revamped water level sensor relies on measuring capacitance changes in a copper strip board when under water rather than detecting a complete circuit like the previous model.

He decided it was time to build his own solution to this problem. What he ended up with was a water level sensor made from PVC pipe and a few other components. The physical assembly is pretty simple.

I was thinking there must be a simple sensor that could tell me when the water level has fallen a set amount and automatically run the "fill pool" zone on the Rachio.

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 system relies on two key components to ...

Liquid level sensor works with simple electronics Researchers at Yokohama National University have created a liquid-based tilt sensor that only needs simple interface electronics – some 10MΩ resistors ...
