1. SENSORS
By: Kamalesh P

2. ACCELERATION SENSOR
✘ Acceleration
sensors or accelerometers let you
make precise measurements of
vibration or shock for a variety of
applications.
✘ They are used to measure vibration,
shock, displacement, velocity,
inclination and tilt.
✘ Our accelerometers are based on
several different technologies and
include piezoelectric, strain gauges,
MEMS, and capacitive sensors.

3. PIR SENSOR
✘ 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.
✘ PIR sensors are commonly used in
security alarms and automatic
lighting applications.

4. TEMPERATURE SENSOR
✘ A temperature sensor is a device used
to measure temperature. This can be
air temperature, liquid temperature or
the temperature of solid matter.
✘ There are different types of
temperature sensors available and
they each use different technologies
and principles to take the temperature
measurement.

5. ULTRASONIC SENSOR
✘ An ultrasonic sensor is an electronic device that
measures the distance of a target object by
emitting ultrasonic sound waves, and converts
the reflected sound into an electrical signal.
✘ Ultrasonic waves travel faster than the speed of
audible sound (i.e. the sound that humans can
hear).
✘ Ultrasonic sensors have two main components:
the transmitter (which emits the sound using
piezoelectric crystals) and the receiver (which
encounters the sound after it has travelled to
and from the target).

6. OXYGEN SENSOR
✘ An oxygen sensor is an electronic device that measures the proportion
of oxygen (O2) in the gas or liquid being analysed.
✘ An oxygen sensor is one type of sensor and it is available in the exhaust system of
an automobile. The size and shape of this sensor look like a spark plug.

7. GPS SENSOR
✘ GPS stands for Global Positioning
System. The system contains satellites
and ground based control installations.
✘ GPS sensor consists of surface mount
chip which processes signals from
GPS satellites using a small
rectangular antenna, often mounted on
the top of the GPS chip.

8. LIDAR SENSOR
✘ LIDAR is a remote sensing method.
✘ LIDAR technology uses the light from
a laser to collect measurements.
✘ These are used to create 3D models
and maps of objects and
environments.

9. MIC SENSOR
✘ The Mic Sensor is an analog input sensor.
It is able to detect noise levels based on air
vibrations.
✘ A Core module can read the voltage value.
Mic Sensor State Table. Noise Level.

10. MQ-2 SENSOR
✘ The MQ-2 is a smoke and combustible gas
sensor . It can detect flammable gas in a range
of 300 - 10000ppm.
✘ It's most common use is domestic gas leakage
alarms and detectors with a high sensitivity to
propane and smoke.

11. VIBRATION SENSOR
✘ A vibration sensor is a device that
measures the amount and
frequency of vibration in a given
system, machine, or piece of
equipment.
✘ Those measurements can be used
to detect imbalances or other
issues in the asset and predict
future breakdowns.

12. PROXIMITY SENSOR
✘ A proximity sensor is a non-
contact sensor that detects the
presence of an object (often referred
to as the “target”) when the target
enters the sensor’s field.
✘ Depending on the type of proximity
sensor, sound, light, infrared radiation
(IR), or electromagnetic fields may be
utilized by the sensor to detect a
target.

13. LDR SENSOR
✘ Photo resistors, also
known as light
dependent resistors
(LDR), are light
sensitive devices
most often used to
indicate the presence
or absence of light,
or to measure the
light intensity.

14. HEART BEAT SENSORS
✘ Heart beat sensors are designed to give digital output heart beat when a finger is
placed on it. When the heart beat detector starts working, the light emitting detector
(LED) blinks simultaneously for every heartbeat.

15. FUEL SENSOR
✘ Fuel sensor is a device designed to
make accurate measurements of
fuel level in vehicle tanks.
✘ According to these measurements a
GPS tracking and telematics
platform features the following data
fuel level in the tank of a vehicle ,
fuel consumption per time period ,
average fuel consumption.
✘ e.g. miles per gallon (mpg) , fuel
refills or drains.

16. AIR SPEED SENSOR
✘ Airspeed indicator, instrument
that measures the speed of an
aircraft relative to the surrounding
air, using the differential between
the pressure of still air (static
pressure) and that of moving air
compressed by the craft's forward
motion (ram pressure);
✘ As speed increases, the difference
between these pressures .

17. FLEX SENSOR
✘ A flex sensor or bend sensor is a sensor that measures the amount of
deflection or bending.
✘ Usually, the sensor is stuck to the surface, and resistance of sensor
element is varied by bending the surface.

18. TOUCH SENSOR
✘ They work like thermostats, and
monitor the temperature of each
room, or zone, that you place them
in your house.
✘ Air Touch receives the temperature
information from your sensors, and
responds by adjusting airflow
where necessary to help maintain
your chosen set point for each
zone.

19. BMP180 SENSOR
✘ BMP180 is one of sensor of BMP XXX series.
✘ They are all designed to measure Barometric
Pressure or Atmospheric pressure. BMP180 is
a high precision sensor designed for consumer
applications.
✘ Barometric Pressure is nothing but weight of
air applied on everything. The air has weight
and wherever there is air its pressure is felt.
✘ BMP180 sensor senses that pressure and
provides that information in digital output.

21. RAIN SENSOR
✘ A rain sensor is one kind of switching device which is used to detect the
rainfall. It works like a switch and the working principle of this sensor is,
whenever there is rain, the switch will be normally closed.

22. MOISTURE SENSOR
✘ Soil moisture sensors measure the
volumetric water content in soil .
✘ Since the direct gravimetric
measurement of free soil moisture
requires removing, drying, and
weighing of a sample, soil
moisture sensors measure the
volumetric water content indirectly
by using some other property of
the soil, such as electrical
resistance, dielectric constant, or
interaction with neutrons, as a
proxy for the moisture content.
