What is Sensor Technology?

Definition and Overview

Sensor technology refers to the use of sensors to detect and measure physical phenomena, such as temperature, pressure, light, and motion. These sensors are designed to convert physical parameters into electrical signals that can be processed and analyzed by computers or other devices. Sensor technology is used in a wide range of applications, from consumer electronics to industrial automation, and is an essential component of the Internet of Things (IoT).

Key components of sensor technology include the sensor itself, which is responsible for detecting physical phenomena, and the signal processing circuitry that converts the electrical signals generated by the sensor into a form that can be analyzed by a computer or other device. Additionally, sensor technology often requires data processing software and communication protocols to enable the transmission of data between sensors and other devices.

To understand how sensor technology works, it is helpful to consider the example of a temperature sensor. A temperature sensor typically consists of a material that changes resistance in response to changes in temperature, such as a thermistor or a resistance temperature detector (RTD). When the temperature of the sensor changes, the resistance of the material also changes, which generates an electrical signal that can be measured and processed by a computer or other device.
