The XBee can detect the water level by testing for a closed circuit between the two electrodes of any sensor module. The water acts as a sort of switch that closes the circuit. When the water ...

The soil moisture sensor module , built around the LM393 comparator, gives an active-low (L) level output when the soil is dry (determined ... for driving high-current/high voltage loads like water ...

Check out the new water level sensor circuit. The simple water level indicator circuit presented here makes this system automatic, i.e. it switches on the pump when the water level in the overhead ...

When the water is below level A, the sensors are both open circuits and the outputs of the comparators are high. When water contacts both terminals of either the upper or lower sensor, a finite ...

Recently, there have been 28 sensors installed throughout Hampton Roads as part of the project. “Water level sensors are basically an automated system that sends a message to the Cloud every six ...

Water level sensors serve an important purpose in rivers, warning of floods and unsafe recreational conditions. A new one is claimed to be not only more robust and reliable than others ...
