Water Level Alarm Indicator [ Diy ] 4 Methods

Water Level Alarm Indicator
In this video, we will see a few methods of making water level alarm / water level Indicator
#1. Water level alarm using NPN Transistor
1)Resistor
10k -2
1M -1
1k -1
2)Transistor
BC547 -2
4)Buzzer(3v-12v)
5)Battery 9v
(Any Power Supply between 3v to 12v can be used)
#2. Water level alarm using IC 555
1)Resistor
10k -1
100k -1
2)Capacitor
4.7uF/16v -1
0.01uF -1
3)IC555
4)Buzzer(3v-12v)
5)Battery -9v
(Any Power Supply between 3v to 12v can be used)
#3. Low Water level alarm DIY
1)Resistor
10k -3
1M -1
1K -1
2)Transistor
BC547 -3
3) LED -1
4) Buzzer(3v-12v)
5) Battery 9v
(Any Power Supply between 3v to 12v can be used)
#4. Water level alarm using TTP223
1) TTP223 Module
2) Resistor
120 ohm -1
220 -2
3) Transistor
2N2222/2N3904/BC547/BC548
4) Buzzer (3v-5v)
5) Battery 3.7v
6) Thin Metal Plate
7) LED -2
8) ON/OFF Switch -1
(Battery having a voltage between 3v to 5v can be used)

[@akhilsankar]

Nice tutorial. Please bring more.

[@benobrien4054]

Great work, can you add a switch to the low level circuit or will I then need to modify the resistor values?

[@SmartcadSoftwareSolutions]

I can say you perfect,
Superb job dude.
Thank you so much for your time and efforts

Nice video. Especially the low water indicator! Well done.

[@DavidKHill]

I have been looking high and low (no pun intended) for a low water detection circuit. I was just about to design an OP AMP version to do a comparator check. (Low impedance inputs) when I stumbled upon this gem. Can you provide the schematic in a PDF so I don't have to fight UA-cam's annoying paused/darken feature? I'll put it into a PDF and send it back you. Cheers!!

Please see description

[@nurulhusna1140]

for the low level indicator , what if i want to add another 2 led , two indicate the water decrease from high to low ?

[@ujjainia123]

One issue with TTP223 touch module...☹️
If continue 10 second sensing then output automatically off ☹️

[@eletrolordcnc4916]

Sensacional.

[@pradeepk7928]

Hello
How can we increase the sound.. should alert 1km far, would that possible ..?

[@snnyhacksci.5984]

with few modifications in the circuit, we can use Car or Truck horn in place of buzzer

[@snnyhacksci.5984]

I have updated the description with related circuit diagram. please see description for detail.. ..thanks

[@ujjainia123]

Possible... If you use a long distance rf transceiver module

[@lrtaralte]

OK, enough of the buzzer system, we already knew that, instead of the buzzer ues a speaker and let it talk out loud ( attention please water tank is full, please shut off the water) something like that.
