A sensor is a device that detects and responds to some type of input from the physical environment. The specific input could be light, heat, motion, moisture, pressure, or any one of a great number of other environmental phenomena. The output is generally a signal that is converted to human-readable display at the sensor location or transmitted electronically over a network for reading or further processing.

Types of Sensors│ Different types of sensors│ Classification of sensor│ Hi everybody, today I will share about Types of Sensor. This video you learn following about Types of Sensor. Sensors are classified based on the nature of quantity they measure. Following are the types of sensors with few examples. 1.

A temperature sensor is a device, typically, a thermocouple or RTD, that provides for temperature measurement through an electrical signal. A thermocouple (T/C) is made from two dissimilar metals that generate electrical voltage in direct proportion to changes in temperature. An RTD (Resistance Temperature Detector) is a variable resistor that will change its electrical resistance in direct proportion to changes in temperature in a precise, repeatable and nearly linear manner.

An infrared sensor is an electronic instrument which is used to sense certain characteristics of its surroundings by either emitting and/or detecting infrared radiation. Infrared sensors are also capable of measuring the heat being emitted by an object and detecting motion.

Types Of Sensors
Speed Sensor
Sensors used for detecting speed of an object or vehicle is called as Speed sensor.
DEVICE USED: Wheel speed sensors, speedometers, ground speed radar, Doppler radar, air speed indicators.

Temperature Sensor
A device which gives temperature measurement as an electrical signal is called as Temperature sensor.
DEVICE USED: Mechanical temperature sensors like Thermometer and Bi-metal.  Electrical temperature sensors like , Resistance thermometer and Silicon band gap temperature sensor.

PIR Sensor
An electronic sensor used for measuring the infrared light radiation emitted from objects in its field of view is called as a PIR sensor or Pyroelectric sensor.
DEVICE USED: Parallax PIR sensor

Ultrasonic Sensor
The principle of ultrasonic sensor is similar to sonar or radar in which  interpretation of echoes from radio or sound waves to evaluate the attributes of a target by generating the high-frequency-sound waves

# data[].attributes.body
A device which gives an output by detecting the changes in quantities or events can be defined as a sensor. Generally, sensors produce an electrical signal or optical output signal corresponding to the changes in the inputs. There are different types of sensors, for example, consider a thermocouple which can be considered as temperature sensor that produces an output voltage based on the input temperature changes.

Temperature Sensor

Temperature Sensor (Thermistor)

Temperature is one of the most commonly measured environmental quantity for different reasons. There are different types of temperature sensors that can measure temperature, such as thermocouple, thermistors, semiconductor temperature sensors, resistance temperature detectors (RTDs), and so on. Based on the requirement, different types of sensors are used for measuring temperature in different applications.

a device which detects or measures a physical property and records, indicates, or otherwise responds to it.

# data[].attributes.body
A sensor is an electronic component, module, or subsystem whose purpose is to detect events or changes in its environment and send the information to other electronics, frequently a computer processor.
Types of sensor:
Speed Sensor:  Speed sensors are machines used to detect the speed of an object, usually a transport vehicle.
Device Used:  Tachometer- It is a sender device used for reading the speed of a vehicle's wheel rotation.

Seismometer :  A seismograph, or seismometer, is an instrument used to detect and record seismic waves.

The coolant temperature sensor is used to measure the temperature of the engine coolant of an internal combustion engine. The readings from this sensor are then fed back to the engine control unit (ECU), which uses this data to adjust the fuel injection and ignition timing.
