Water Level Indicator Alarm for Water Tank:
Water Level alarm circuit is made by BC547 Transistors, in this circuit four transistors are used. In this circuit transistor used as a simple amplifier and 9V battery used as a power source and three LEDs are indicating purpose like water level condition of the water tank. This project making simple at home purpose and small school projects because the circuit having only a resistor and transistor combination no complexity in the circuit.

How its Work water level indicator:
Water level indicator circuit working is simple to understand the circuit shown above like this, it has four inputs for making this circuit. The inputs are A, B, C and D which are immersed in the water tank, but in this project, we used water glass used in place of water tank for testing purposes. Here all the inputs keep inside tank with different positions like Low, Middle, Top and Overflow. 9 volts supply directly immersed in tank below position which position is empty Tank, another position A called 25% tank full, another position B called 50% tank full and C called Full Tank position and final position is overflow which is D. 9 volts toches the "A" and indicates lower LED and touches the "B" position LED middle will glow which means tank reaching Half Tank and 9 volts wire touches position "C" and indicates Green LED which means Tank Full and finally touches the "D" and Buzzer will ON and Alarm ring starts.
