Sensor: The Bridge Between the Physical and Digital Worlds
A sensor is a device that detects and responds to some type of input from the physical environment and converts it into a measurable signal, typically an electrical signal (analog voltage or digital code). In essence, sensors act as the "senses" of electronic systems, bridging the gap between the physical world and the digital world for measurement, monitoring, and automated control.
How a Sensor Works
The primary function of a sensor involves a process called transduction, which is the conversion of one form of energy into another. The basic operation involves a few key steps:
Receptor/Sensing Element: This part of the sensor is exposed to the environment and detects the physical input, such as heat, light, pressure, or motion.
