What Are Sensors and How Do They Work? - TechTarget What is a sensor? A sensor is a device that detects and responds to some type of input from the physical environment The input can be light, heat, motion, moisture, pressure or any number of other environmental phenomena
SENSOR Definition Meaning - Merriam-Webster The meaning of SENSOR is 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 a Sensor? Different Types of Sensors, Applications In this article, we’re going to talk about what a sensor is, what it can do, and how it can be used in process control You’ll also learn the various applications of sensors in industrial environments
What Is A Sensor, and How Do Sensors Work? - The Knowledge Academy A Sensor is a device that identifies changes in the physical environment, like temperature, light, pressure, or movement Then, it will turn those changes into signals that a machine can understand or into a human-readable format
What is a Sensor? - Monolithic Power Systems Fundamentally, a sensor is an apparatus that recognizes occurrences or modifications in its surroundings and then generates a corresponding signal Usually, this output is presented as an optical or electrical signal
What is a sensor? - YoungWonks A sensor is an input device that shares an output in the form of a signal with regards to a particular physical quantity (aka input) In other words, it is a device that converts signals from one energy domain to electrical domain
Sensors | NIST By their very definition, sensors are devices that measure or detect things such as light, heat and electric current That’s why NIST, as the nation’s measurement science institute, has been in the sensor business since its earliest years
