2. What is a Sensor?What is a Sensor?
A sensor is a device that detects the changes in electrical or physical or other
quantities and thereby produces an output based on the pre-set values entered or the
current conditions.

3. Ultrasonic sensorUltrasonic sensor

4. • In industrial applications, ultrasonic sensors are characterized by
their reliability and outstanding versatility. Ultrasonic sensors can be used
to solve even the most complex tasks involving object detection or level
measurement with millimetre precision, because their measuring method
works reliably under almost all conditions.

5. • A passive infrared
sensor (PIR sensor) is an
electronic sensor that
measures infrared (IR) light
radiating from objects in its
field of view. They are most
often used in PIR-based
motion detectors.

6. Temperature sensorTemperature sensor

7. • The TMP36 is a low voltage, precision centigrade temperature sensor. It provides
a voltage output that is linearly proportional to the Celsius temperature. It also
doesn’t require any external calibration to provide typical accuracies of ±1°C at
+25°C and ±2°C over the −40°C to +125°C temperature range. We like it
because it’s so easy to use: Just give the device a ground and Ethernet port to
screen for reading and read the voltage on the V out pin. The output voltage
can be converted to temperature easily using the scale factor of 10 mV/°C.

8. Speed sensorSpeed sensor
• Speed sensors are machines used
to detect the speed of an
object, usually a transport vehicle

9. Blind spot monitorBlind spot monitor
• A blind spot monitor is a vehicle-
based sensor device that
detects other vehicles located to
the driver’s side and rear.
Warnings can be visual,
audible, vibrating.
• It can also include “cross traffic
alerts”.

10. Radar gunRadar gun
• A radar speed gun is a device used to measure the
speed of moving objects. It is used in law-
enforcement to measure the speed of
moving vehicles and is often used in professional
spectator sport, for things such as the measurement
of bowling speeds in cricket, speed of
pitched baseballs, athletes and tennis serves.
• A radar speed gun is a Doppler radar unit that may
be hand-held, vehicle-mounted or static. It measures
the speed of the objects at which it is pointed by
detecting a change in frequency of the returned
radar signal caused by the Doppler effect, whereby
the frequency of the returned signal is increased in
proportion to the object's speed of approach if the
object is approaching, and lowered if the object is
receding.

11. Water sensorWater sensor
• The Water in Fuel Sensor or WiF
sensor indicates the presence of
water in the fuel. It is installed in
the fuel filter and when the
water level in the water
separator reaches the warning
level, the Wif sends an electrical
signal to the ECU or to
dashboard (lamp). The WiF is
used especially in the Common
Rail engines to avoid the Fuel
injector damage.

12. Oxygen sensorOxygen sensor
• An oxygen sensor (or lambda sensor) is an electronic device that measures the
proportion of oxygen (O2) in the gas or liquid being analysed.
• It was developed by the Robert Bosch GmbH company during the late 1960s
under the supervision of Dr. Günter Bauman. The original sensing element is made
with a thimble-shaped zirconia ceramic coated on both the exhaust and
reference sides with a thin layer of platinum and comes in both heated and
unheated forms. The planar-style sensor entered the market in 1990, and
significantly reduced the mass of the ceramic sensing element as well as
incorporating the heater within the ceramic structure. This resulted in a sensor that
started sooner and responded faster.

14. GyroscopeGyroscope
• A gyroscope is a spinning wheel or
disc in which the axis of rotation is
free to assume any orientation.
When rotating, the orientation of this
axis is unaffected by tilting or
rotation of the mounting, according
to the conservation of angular
momentum. Because of this,
gyroscopes are useful for measuring
or maintaining orientation.

15. MRIMRI
• Magnetic resonance
imaging (MRI), nuclear magnetic
resonance imaging (NMRI), or magnetic
resonance tomography(MRT) is
a medical imaging technique used
in radiology to investigate
the anatomy and physiology of the
body in both health and disease. MRI
scanners use magnetic fields and radio
waves to form images of the body. The
technique is widely used in hospitals for
medical diagnosis, staging of disease
and follow-up without exposure
to ionizing radiation.
