3. 1] WhaT iS SenSor ?
Sensor are devices that convert physical
parameters or conditions into a signal
that can be measured electrically
.

4. 2] How sensor work
Light trnsmiter is an LED which radiates or infra red light .it
is sterred by generator to pulsing operation to create to high
radiation intensity for a short period. An object reflects
radiated light on to the receiver (photo diode and photo
transistor )
the signal received amplified and is synchronized with
the generator signal .this mode of signal evaluation result in
a distortion reduction . The signal will be integrated I the
comparator afterwards . In case signal exceed certain level
the output switches and function reserve indicator
activated . If required timers and functions reserve indicator
can be arranged before the output .

7. 4] Role of sensoRs in
automation
 Automation plays big role in world application like the
manufacturing of cars, planes and electronics the
preparation and packaging of foods and beverage &
processing of chemicals, oil and gas .
 Sensors are used in a wide range of control system that
makes lives for people easier , safer and moreproductive
both at work and at home through automation
 Automation is not possible without sensors
