nciple:

This circuit uses a popular timer I.C 555. I.C 555 is connected as comparator with pin-6 connected with positive rail, the output goes high(1) when the trigger pin 2 is at lower then 1/3rd level of the supply voltage. Conversely the output goes low (0) when it is above 1/3rd level. So small change in the voltage of pin-2 is enough to change the level of output (pin-3) from 1 to 0 and 0 to 1.
The output has only two states high and low and cannot remain in any intermediate stage. It is powered by a 6V battery for portable use. The circuit is economic ..................[:=> Show Contents <=:]

in
the tank. The
motor remains
‘on’ even when
the water level
crosses sensor

As water in
the tank rises to
touch sensor H, timer IC2 is retriggered
at pin 6 via inverters N3
and N4 and as a result, its output
goes low. The relay de-energises and
the motor stops filling water in the
tank. The motor remains ‘off’ even
when the water level falls below sensor

As water is consumed and its level
falls below sensor L, the motor restarts.
Thereafter, the cycle repeats.
You can also manually start and
stop the motor using switch S1.
