Water Level Alarm Circuit

[purifier]

I need a very simple Water Level Alarm Circuit. I just need to know when the water reaches a particular level in a glass. I just have a normal bell with me, battery operated. I want to use this. Can someone help me as to what I should do to make it work?

Well...I've seen that... But I just wanted a very simple one... Imagine water acting as a short between the two terminals.... I tried it but its not ringing... It works only when I attach a small steel piece to the positive terminal...

If your water is clean, it will not conduct electricity enough for you to make a bell ring.

You could make a floating ring with a magnet on a pole, and use a reed switch to activate your bell.

Another way is to make the floating device push a rod on a microswitch to activate this.

you need a cmos 4011 chip cmos atleast
this negates any problems with conduction


and also switch the relay if needed for your bell using a transistor
fed by this cmos chip

a good tip is to look for circuits
using the search string

Oh thank you so much... Will start analysing that and will modify it to my needs... Thank you once again.
