In the broadest definition, a sensor is a device, module, machine, or subsystem that detects events or changes in its environment and sends the information to other electronics, frequently a computer processor.
An analog sensor produces a signal that varies with the force applied, while a digital sensor converts this signal into readable data. Strain and weight sensors are used in many areas.
Sensors, detectors, and transducers are devices designed to measure, detect, or respond to specific physical, chemical, or environmental changes. These devices often rely on specialized electronics or sensitive materials to detect the presence of a particular entity or function.
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.
