water level sensor circuit
For circuit not only indicates the amount of water in the tank head, but also gives an alarm when the tank is full.
This circuit uses the widely available to show IC number CD4066 bilateral switch CMOS IC to the water level through LEDs.
If the water is empty the wires in the tank are open circuit and the 180K resistors pulls the switch to open the little switches and LEDs are off. When the water begins to fill the first wire connected to the reservoir in the S1 and the + supply are shorted by water. This closes the S1 and turns the LED1 ON. As the water further into the tank, LEDS2, 3 to 4 pm light gradually filled.
No. Levels of the display to 8 if 2 can CD4066 ICs are used to increase similarly.
If the water is full, the base of the transistor BC148 is pulled up with water and saturate the transistor, turning the buzzer ON. The SPST switch has to be opened to turn off the ringer.
Remember, the switch ON while pumping water otherwise the buzzer does not sound!

how to power supply of water level detection circuit?? pls pls tell me i make this circuit but i cant understand how to get power supply pls pls reply me
is this circiut really working ?????
because me and my classmates had a project and we decided to make this…..
This is simple circuit “kristian” and it is old circuit which had verify already.
@Mehul you like to know to supply power to the circuit? I designed the circuit for my school project and I used four 1.5 AA batteries. They make up 6V…
plz can u send me that logic gates diagram of that circuit………plz
can we use any other transistor instead of bc148
i have made this circuit but i cant get outputs because i dnt have bc148 & i have used another npn transistor
and please cnfirm me one more thing that thi circuit will work on D.C or A.C and why??
please give me clear details about wires used i.e.,type of wire used aluminium or copper or sensors etc..
i need to construct a sequential switch, can you guys help me make a circuit using cd4066?pls..pls..pls..
