This document discusses different types of sensors. It defines a sensor as a device that detects inputs from the environment, such as light, heat, motion, and produces a readable output signal. It then lists and provides brief descriptions of common sensors, including temperature, proximity, accelerometer, IR, pressure, light, ultrasonic, smoke, gas and alcohol, touch, color, humidity, tilt, and flow and level sensors. Each detects a specific property and works based on converting the detected input into an electrical signal.

2. SENSOR
A sensor is a machine that detects and reacts to
some kind of input from the objective
environment. The precise input might be light,
heat, motion, moisture, pressure, or any one of a
huge number of additional environmental
occurrences. The output is usually a signal that
is transformed to human-readable exhibit at the
sensor site or broadcasted electronically above a
network for evaluation or further dispensation.

3. DIFFERENT TYPES OF SENSOR
Different types of sensors that are commonly
used in various applications are following.
 Temperature Sensor
 Proximity Sensor
 Accelerometer
 IR Sensor
 Pressure Sensor
 Light Sensor
 Ultrasonic Sensor
 Smoke, Gas and Alcohol Sensor

4. DIFFERENT TYPES OF SENSOR
 Touch Sensor
 Color Sensor
 Humidity Sensor
 Tilt Sensor
 Flow and Level Sensor

5. TEMPERATURE SENSOR
A Temperature Sensor is a machine which is used to
determine heat or temperature on the operating
device part. Temperature sensing is executed by
device called Thermocouple. A thermocouple is a
temperature-measuring machine consisting of two
different conductors that get in touch with each other
at one or more points. It generates a voltage when the
temperature of one of the summits differs from the
suggestions temperature at other parts of the circuit.

6. PROXIMITY SENSOR
A proximity sensor notices the presence of objects
that are almost placed without any end of
contact. Since there is no contact connecting the
sensors and sensed object and require of
mechanical parts, these sensors have long useful
life and high reliability.

7. ACCELEROMETER
An accelerometer is a machine that
computes proper acceleration. Proper speeding
up, being the acceleration remains in its own
immediate rest frame, is not the same as
organize acceleration, being the acceleration in a
permanent coordinate system.

8. IR SENSOR
This smart tool is used to sense the infrared lights.
Infrared sensor imagines the heat leaks in houses;
recognize environmental substances in the environment,
and helping doctor to calculate patient blood flow. It can be
included with wearable electronics. A very simple example,
all the remotes having IR sensor, it’s use to pass the power
to particular devices, like TV remote, fan remote, vehicle
key remote all having infrared sensor.

9. PRESSURE SENSOR
A pressure sensor is a machine for pressure
capacity of gases or liquids. Pressure is an appearance of
the force necessary to stop a fluid from increasing, and is
frequently stated in terms of strength per unit area. A
pressure sensor usually be active as a transducer; it makes
a signal as a purpose of the pressure forced.

10. LIGHT SENSORS
Light Sensors are photoelectric machines that change
light energy whether noticeable or infra-red light
keen on an electrical signal.

11. ULTRASONIC SENSOR
An Ultrasonic Sensor is a non-contact kind machine that can
be used to calculate distance as well as speed of an entity. An
Ultrasonic Sensor works based on the belongings of the sound
impression with frequency larger than that of the person
audible range.

12. SMOKE, GAS AND ALCOHOL
SENSOR
A Smoke Detector is a burn sensing machine that point to fire.
Smoke Detectors are incredibly common in homes, offices, schools
and business. Smoke Detectors are very helpful machine as the
harm caused by fire mistake is catastrophic.

13. TOUCH SENSOR
A Touch Sensor is a kind of sensor that notices physical touch
or nearness. They are input machine like buttons and switches
although are more responsive than those two. Hence, touch
sensors are changing buttons in machine like mobile phones
and laptops

14. COLOR SENSOR
A Color Sensor, as the name implies, is a machine that
senses or identify colors. A color sensor will employ an
external means of producing light and then examine the
reflected light from the entity in order to decide its color.

15. HUMIDITY SENSOR
Humidity Sensor is one of the mainly important machines
that have been broadly in consumer, manufacturing,
biomedical, and ecological etc. applications for calculating
and examining Humidity.

16. TILT SENSOR
A Tilt Sensor is a element that notices direction of an
object. One of the best instances for the application of
a tilt sensor is its employ in aircrafts.

17. FLOW AND LEVEL SENSOR
It’s employ to detect the height of liquids and added fluids,
containing granular equipment, slurries and powder that
show an upper free outside. Level sensors is as well using
for water squander management and recycling reason, like
it’s employing to determine water tank levels, petrol fuel
measuring, high or low level alarm, liquid possessions
inventory and irrigation control.
