Global Sensor Market Overview

A sensor is a device that detects changes in physical, chemical, or biological conditions—such as temperature, pressure, motion, light, humidity, or chemical composition—and converts this information into signals that can be processed by machines or interpreted by humans. Sensors enable real-time monitoring, automation, feedback control, and predictive analysis across a wide range of applications.

Today, sensors are deeply embedded in everyday life. From smartphones, wearable devices, and smart home systems to automobiles, factory automation equipment, and medical diagnostic tools, sensors form the backbone of modern technology systems.
