automatic water level controller powerpoint presentation

Automatic control is the application of control theory for regulation of processes without direct human intervention. In the simplest type of an automatic control loop, a controller compares a measured value of a process with a desired set value, and processes the resulting error signal to change some input to the process, in such a way that the process stays at its set point despite disturbances. This closed-loop control is an application of negative feedback to a system. The mathematic ....etc

WORKING PRINCIPLE:



Attach length copper wire to one stick and make two points (top and bottom) on other stick with copper wire; and mark them point A, B, C as shown in the diagram. Connect points A, B and C to the main circuit. The IC 555is used in the circuit as an astable multivibrator. The IC is an 8pin duel-in-line IC. When there is water in between the points A and C, pin no 3 voltage of the IC becomes high and transistor BC 148 operates the relay. As a result the motor starts ....etc

SIMPLE AUTOMATIC WATER-LEVEL CONTROLLER


Water-level controllers are
common nowadays. The
one described here is
built around timer NE555 and
inverter buffer CMOS IC CD4049.
It uses readily-available, low-cost
components, and is easy to build
and install on the over-head
tank (OHT) to prevent wastage of
water.

The circuit works off a 12V battery
or 230V AC mains using a 12V
adaptor. The three sensors built
from non-corrosive metal are fitted
to the OHT as shown in Fig. 2 and
conn ....etc
