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 ...

The circuit finds use in a variety of places ... in the water and the IC output is high. As soon as the water level drops below sensor B (lower-level sensor), the output state of the IC changes ...

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 ...

[Raikut] made this process a lot easier by designing an LED bar indicator to monitor the water level. The sensor is very simple. Each LED is basically its own circuit controlled by a transistor ...

A low-voltage electronic circuit that senses upper and lower ... receive the necessary hysteresis. As the top sensor goes low (water above level C), the CLR signal is activated and the output ...

This simple water level indicator will activate an active buzzer (e.g. BeStar BPT-23CX ) in order to make a noise when a certain level of water is being reached. Because the water sensor and the ...
