What is sensor in simple words?
1 : a device that responds to a physical stimulus (such as heat, light, sound, pressure, magnetism, or a particular motion) and transmits a resulting impulse (as for measurement or operating a control)
What is sensor explain?
A sensor is a device that detects the change in the environment and responds to some output on the other system. A sensor converts a physical phenomenon into a measurable analog voltage (or sometimes a digital signal) converted into a human-readable display or transmitted for reading or further processing.
What is sensor example?
The simplest example of a sensor is an LDR or a Light Dependent Resistor. It is a device, whose resistance varies according to intensity of light it is subjected to. When the light falling on an LDR is more, its resistance becomes very less and when the light is less, well, the resistance of the LDR becomes very high.
How does the sensor work?
How do sensors work? Put simply, a sensor converts stimuli such as heat, light, sound and motion into electrical signals. These signals are passed through an interface that converts them into a binary code and passes this on to a computer to be processed.
What is the purpose of sensor?
In the broadest definition, a sensor is a device, module, machine, or subsystem whose purpose is to detect events or changes in its environment and send the information to other electronics, frequently a computer processor. A sensor is always used with other electronics.
What are the types of sensor?
List of Sensors

- Temperature Sensors.
- Radiation Sensors.
- Proximity Sensors.
- Pressure Sensors.
- Position Sensors.
- Photoelectric Sensors.
- Particle Sensors.
What is the difference between sensor and detector?
Sensor is a tool that responds to the quantity of input by making a functionally associated output generally in the electrical form or optical signal. A detector is a tool that picks up information of interest controlled in a modulated wave.
What is the difference between sensor and sensor?
The main difference between a sensor and a transducer is the output signal….Comparison between a sensor and a transducer.
|Examples||Pressure switch, thermistors, mercury thermometers, motion sensors.||Pressure transducer, cable extension transducer, linear transducer, microphone|

WHAT IS sensor and its application?
The sensor is an electronic device that measures physical attributes such as temperature, pressure, distance, speed, torque, acceleration, etc., from equipment, appliances, machines and any other systems. Applications classify sensors, Property sensed, Technology used and Systems where they are deployed.
Is detector a sensor?
In DIN 1319-1, a detector is called a transducer, also known in Europe as a sensor, so that in the literature rather than referred to as an infrared detector, the terms infrared transducer and infrared sensor are often found.
Can a transducer be a sensor?
Both a sensor and a transducer are used to sense a change within the environment they are surrounded by or an object they are attached to, but, a sensor will give an output in the same format and a transducer will convert the measurement into an electrical signal. …
What is the definition of a camera sensor?
CAMERA SENSOR DEFINITION What is a camera sensor? A camera sensor is a piece of hardware inside the camera that captures light and converts it into signals which result in an image. Sensors consist of millions of photosites, or light-sensitive spots that record what is being seen through the lens.
Where does the word ” sensor ” come from?
Origin: Originated 1925–30 from sense + -or. A sensor is a converter that measures a physical quantity and converts it into a signal which can be read by an observer or by an instrument.
Do you need to know the sensor size of a camera?
Camera sensor size is definitely something to consider when renting or purchasing a camera. The image quality and the flexibility of what kinds of images you can capture is directly related to your camera’s sensor. So how exactly does camera sensor size matter? Let’s take a closer look. Does a camera’s sensor size matter?
What does the sensitivity of a sensor mean?
A sensor’s sensitivity indicates how much the sensor’s output changes when the measured quantity changes. For instance, if the mercury in a thermometer moves 1 cm when the temperature changes by 1 °C, the sensitivity is 1 cm/°C. Sensors that measure very small changes must have very high sensitivities.
What is sensor and what are different types of sensors?
An electronic sensor can be designed to measure one of many variables. Types of electronic sensors include force sensors, light detectors, tilt sensors, and passive infrared (PIR) sensors. The many varieties of these sensors operate on the principle of making measurements based on changes in an electrical signal.
What kind of a device is a sensor?
Sensor Device is a type of input device which do some processing and generates output. The other meaning of sensor device is that it is a type of device which convert signals from one source of energy to the electrical domain. One of the sensor examples is a Light Dependent Resistor (LDR). In LDR the resistance varies according to light intensity.
What is sensor in scientific terms?
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.
What is best sensor?
- alarms or smart home
- Hue Motion Sensor.
- Fibaro Motion Sensor.
