In the water level sensor schematic, the common probes connecting the underground tank and the overhead tank to +9V supply are marked ‘C’. The other probe in underground tank, which is slightly above ...

Objective To create an efficient water level monitoring system using an HC-SR04 sensor and Arduino, enabling real-time data collection, visualization, and potential IoT integration for various ...

Since the traditional water level controller has inherent problems, many people prefer digital electronics to detect and control the water level in an intelligent manner. Here is a simple yet ...

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.

And, the SCR's trigger is connected to sensor A for detecting the water's upper level. The anode, C, which is connected to the +12-V supply, is kept at the lowest water level, below B.
