Due to corrosion on the sensor points( due to high current flow) such circuits are not recommended, rather use Microcontroller/OpAmp based circuits where very low current flows through the sensor lines.

@@peterfitzpatrick7032 That's okay if you want to stop the corrosion. However, when you add salt to the water to increase it's conductivity and then apply a current, you split NaCl to Na and Cl. And - maybe you guessed it - get chlorine gas. Which is not really great due to its poisoness. Using a proper circuit is definetly a better option.

After 1 month due to electrolysis, the exposed parts of the wires will dissolve in the water and disappear. Why do you lie to people?

you can see electrolysis occurring at your anode due to the relatively high current needed to drive the LED. Transistors are cheap and the gate current necessary is much lower.

Hi, very simple and looks effective way to detect the water level. Just a query, have seen other videos too and others have used transistors where I dont see that in ur video? Is it mandatory or what is the use of transistors?

@ElectrotechysMedia

2 жыл бұрын

Yes its mandatory to use transistor. A transistor provides proper biasing voltages to switch its load from its high sensitive base terminals. Also note that water is not a good conductor of electricity. So if we directly place wires voltage will be lost in the form of high resistance, to drive directly an led its not sufficient .if we put some salt in water conductivity increases.

@@ElectrotechysMedia I made a device with some DC connected LED indicators to know water level of Ground Tank. A simple device, power supply leads negative to bottom of Water Tank and different levels set at 4 leads and will be connected through raising water levels. All my test with LED indicators and power supply was good before the installation and glowing according to Water Level. But when installed, instead of specific LEDs to glow according to water level, all the indicators are glowing. What is the reason please ? Any diode to be connected.. No idea?

Bro it's not working properly because pure water is not a good conductor of electricity. For electrical conductivity , we need ions in water.. we can add salt to increase electrical conductivity. This circuit only works with salty water or we can say ionised water...But for pure water, we have to add transistors to the circuit. Talking about resistor..apply Kirchoff voltage law..then you can easily calculate resistor value for led
