Water Level Alarm


Water Level Alarm circuit diagram
More explanation about water level circuit, please go to this page.

This circuit will trigger with any fluid with a resistance under 900K between the maximum separation distance of the probes. Let me explain further. The circuit uses a 4050B CMOS hex buffer working on a 5 volt supply.

Hi,I'm interested about your circuit.I just want to ask that can I disregard ng switch and directly tap the output of the hex buffer to the input of CMOS 4011B IC?
