Simple Water Level Controller Using IC-4049 and IC-555

Here, I am going to show you that, how you can make a simple water level controller using IC-4049 and IC-555.

Components To Replace With Sensors....

1. The Short Terminal of Both Switch is the longest wire in the tank.
2.  First Switch (Connection from R5 resistor) is the shortest wire in the tank.
3. Second Switch(Connection from R6 resistor) is medium length wire, which is just below the longest wire(1 inch short from long wire).

Components to Replace With Motors....

1. Bulb is replaced by the motor.

Working...

1. The longest wire is not connected to both wire, then motor is running.
2. If the longest wire is connected to medium length wire, then motor is also running.
3. If the longest wire is connected to both wire, then motor stops running.
4. Same as tank goes empty....and the longest wire is disconnected to medium length wire, then motor don't start.
5. If the longest wire is disconnected to both wire, the motor starts running.
