What is a Sensor?

Sensors or  Detectors are the devices that is used to convert a physical parameter into a signal that can be measured or monitored. For example a GAS Sensor monitors gas concentration (PPM) and converts it into electrical signal that can be measured. The input parameter can be different like Light, Temperature, Humidity pressure etc but the output is generally a human readable or electrically monitarable.

Definition of Sensor:

According to Oxford Dictionaries definition of Sensor is “A device which detects or measures a physical property and records, indicates, or otherwise responds to it.”

Meaning of Sensor as per Wikipedia “A sensor is an object whose purpose is to detect events or changes in its environment, and then provide a corresponding output”

Types of Sensor:

A sensor is classified based on various aspects such as

Application Based: Industrial Sensor, Automotive Sensor etc
Output Based : Resistive output, Differential Output, Differential output, voltage output etc
Parameter Sensing Based: Light, Temperature etc
Most commonly sensors are are classified on Stimulus basis i.e. Sensing Parameter based. Here is a List of most commonly available sensors
