Simple Automatic Water Level Controller Circuit Diagram. Automatic Water Level Controller Circuit Diagram Using 555 timer Ic For Overhead Tank. Automatic water-level controller circuit Leaf switches S1 and S2 used in tape recorders are fixed at the top of the sensor units such that when the floats are lifted the attached 5mm dia.
The 12V DC power supply is given to probe C which is the limit for minimum water always stored in the tank. As a result transistor T1 gets forward biased and starts conducting. Automatic Water Level Controller Circuit Diagram Using 555 timer Ic For Overhead Tank.
Here we have created 4 levels low medium high and full we can create alarms for more levels.
The circuit I am going to share in this post controls water level in the overhead tank or any tank. Connect three 1K resistors to the pin 15 13 and 10 of ULN 2003 IC as shown in the circuit diagram. As the name depicts a water level controller is an automatic device used to monitor a particular level of water for example in an overhead tank and restrict it from exceeding the limit. This can be used both in industries and houses.
