Outlines
3. 01 A Sensor is device which is used to sense the
surroundings of it & gives some useful information about
it.
02 A Sensor acquires a physical parameter and converts it
into a signal suitable for processing(e.g.
optical,electrical,mechanical).
03 “A Sensor is a device that detect and responds to some
type of input from the physical environment”.
04 The input can be light,heat,motion,moisture,pressure
or any number of other environmental phenomena.
05 Sensors Examples:-
Face lock,Fingerprint lock,fire alarm system.
Sensor
4. 01 An Infrared Sensor is an electronic device,that emits in order to
sense aspects of surroundings.
02 An IR Sensor can measure the heat of an object as well as
detects the motion.these types of sensors measures only infrared
radiation.
03 These types of radiations are invisible to our eyes that can be
detected by an infrared radiations.
04 IR Sensor is also called IR Blaster or Remote Sensor.
05 IR Sensor Examples:-
Tv Remote,Set top box
Used in motion based system,home security systems.
7. Automatic Hand Sanitizer Dispenser
The virus is transmitted through direct contact with respiratory
droplet of an infected person(generated through coughing and
sneezing) and touching surfaces contaminated with the virus.
Is Hand sanitizer effective against COVID-19? Everyone
use sanitizer in a public place, if corona will happen to
some person, then it can happen to others through
sanitizer.
Automatic hand sanitizer has touch less operation which
makes people fearless and more confidence about the
sanitization process.

10. 1.
• Automatic hand sanitizer dispensers use sensors. These
sensors know when you’re placed your hands into the
dispensing area and when to dispense the hand gel.
2.
• Traditional infrared sensors have an LED and a receiver. When
you place your hands under the dispenser, the infrared light
from the LED reflects off your hands and is detected by the
receiver.
working
11. 01 Their low power requirements make them suitable for most
electronic device such as laptops,telephones,PDAs.
02 Infrared Motion sensor detects motion in daytime & night time
reliably.
03 It has reaction time quicker than thermocouple.
04 It provides secure communication.
05 The Sensor doesn’t need any contact with the item to be
detected.
Advantages of IR Sensor
12. 01 IR Waves at hight force can harm eyes.
02 Limited Range.
03 Can be affected by environmental conditions such as
rain,fog,dust,pollution.
04 IR Sensor does not work in sun light.
05 Works very little in dark body.
Disadvantages of IR Sensor
13. 01 Radiation Thermometers.
02 Art History & Restoration.
03 Burglar Alarm .
04 Human Body Detection.
05 Item Counter.
