Water Level Indicator DIY Kits (Not Soldered)

₹74.00
Tax included

A water level indicator is used to indicate the level of water in an overhead tank. This keeps the user informed about the water level at all times and avoids the situation of water running overflow. Four LEDs to indicate the 4  different water level positions through BC547.

Please note that  DIY kit is not a project and a commercial product . It's a simple science project to learn Electronic circuit.

S1, S2, S3 and S4 are the four probes for different positions of the water tank. When any of the probes touch the water circuit will be closed and voltage coming to the base of the transistor(the base current Ib get increased by current passing through the water), LED goes ON. So easily we can understand water in the tank is in corresponding water position. 100k Resistor is used to pull down the base of the transistor(Not to produce a false result). If direct Vcc voltage coming into the base of the transistor, It may affect the transistor(So 1k is provided series to the base to limit the base current to micro amperes ).

 Kit Include:

BC547 Transistor.

Four LEDs.

Resistors 1k,100k.
