2. SENSOR
A Sensor is a device that measures a physical quantity and converts it
into a signal which can be read by an observer or by an instrument .
Example - We can say that our skin, ears, eyes and nose are also a
sensor because theycan sense touch , heat , cold , light , noise and
smell .

3. CLASSIFICATION OF
SENSOR
According to power or energy
supply requirement to sensor.
According to various measurement
objective.
According to principle of operation.
According to Output Signal .

4. ACTIVE SENSOR
DIGITAL
TIME
CAPSULE
Sensors that require power supply are called as
Active Sensors
Example: LIDAR
(Light detection and ranging), photoconductive cell.
4
PASSIVE
SENSOR
Sensor that do not require power supply are called Passive
sensor.
Example : Hg thermometer etc.

5. ANALOG
SENSOR
DIGITAL TACHOMETER
o Analog sensor produce continuous signals that are
proportional to the sensed parameter.
o Example: analog tachometer etc...
5
DIGITAL
SENSOR
Digital sensor produce digital outputs that can be directly
interfaced with the digital controller.
Example: Digital tachometer etc...
ANALOG TACHOMETER

6. TEMPERATURE SENSOR
A device which gives temperature measurement as an electrical
signal is called as temperature sensor.
Example: Thermistors, thermocouples etc.
Application: Digital thermometer, in boiler, furnaces, gas turbine
etc...
6
PRESSURE SENSOR
A pressure sensor measures pressure, typically of gases or liquids. A pressure
sensor usually acts as a transducer; it generates a signal as a function of the
pressure imposed. such a signal is electrical.
Example: barometric, piezo resistive pressure sensor etc.
Application: in boiler, in gas turbine etc.

7. LEVEL SENSOR
Level sensors detect the level of liquids In the tank or
container.
Example: Magnetic and mechanical float, pressure
transducer, Pneumatic, Capacitance, load cell etc.
Application: oil-water tank, Pressure transducer boiler,
etc...
7
DISPLACEMENT SENSOR
Displacement sensor is used to measure the distance
and position.
Example: capacitive sensor, Eddy current sensor,
Inductive sensor(LVDT) and etc..
Application: various industrial application, robotics,
and etc...
LEVEL SENSOR

8. INDUCTIVE SENSOR
ULTRASONIC SENSOR
8
An proximity (inductive) sensor is an electronic proximity sensor,
which detects metallic objects or any things without touching
them.
Application: metal detector, traffic
lights, car washes and etc.
Ultrasonic sensors work on a principle similar to
radar or sonar, which evaluate attributes of a target
by interpreting the echoes from radio or sound
waves respectively.
Application:
Industrial used (NDT). In ship and etc...

9. LIGHT SENSOR
A Light Sensor is something that a robot can
use to detect the current ambient light level i.e.
how bright/dark it is.
Example: Photoresistors, Photodiodes,
Phototransistors
Application: CRO, Cameras and Mobile
Phones, etc...
