Introduction: WATER LEVEL INDICATOR

Picture of WATER LEVEL INDICATOR

Hi, iam cj from india.i am going to tell u guys about how to make a liquid level indicator easily with simple items available near your shop.

Step 1:

Picture of

dia 1:this is the cicuit diagram.from this it is easy to fit the circuits in pcb.

Step 2:

Picture of

dia:2:In this diagram the components for this projects is shown and is named.you need the following components to work this project.

resistors:      no.of.items              
  27k                 1
  10k                  2
  150E               1
ceramic capacitor:
      0.01MFD{1}

IC-555{1}
LED red or green -1

Step 3:

Picture of

dia:3 I have fitted these things in spring breadboard for easy checking whether it works or not. it works.
        so, first check the circuits are fitted in correct order using bread board and finally fit it in a pcb.

Step 4:

Picture of

dia:4 I have wired all these things. it worked.

Step 5:

Picture of

dia:5 I have made mine by using a black plastic board since i don't have an pcb.so i used a single wire for joining those circuits.to do it i removed a wire covering from a 9 cm wire.then i took those metalstrings out
and twisted and soldiered in the circuits and i laminated them with cello tape to avoid short circuits.thank you.

can I use it like gasoline level indicator?

carmel1 (author)supliandes2011-05-07

no...u cant..but u can use a gas sensor to make a gasoline level indicator...

supliandes (author)carmel12011-05-10

Thank's. you know were I can found one.

carmel1 (author)supliandes2012-05-28

it depends on your location...u can get it in electrical shops or some other shops

can u tell me the source voltage and describe about the circuit briefly..that is how it works.thank u

carmel1 (author)yashbarmecha2012-05-20

the source volatage is 9v or less than 9 will work..i have explained briefly already...if u want more just tell me which part should i need to explain..

I see a nice gauge, but I don't see how the circuit connects to the gauge. How does it sense the level. Does it only sense when the wire's close the circuit?

the guage is no use..the leds detect the level of water.....
