Sensors are integral concents in various applications, helping to convert fyzical fenomena into meliurable signals. Understanding thee different type of sensors is crial for students and educators in te fields of science and commerering. This article delves into common sensor types, including thermocouples, photodetectors, and more.

Co je to Sensor?

A sensor is a device that detects and responds to o input from the fyzical environment. This input can ben in than form of light, heat, motion, hydrate, pressure, or any theor fyzical acredity. Te output of a sensor is typically an electrical signal that can bee read by an instrument or processed by a computer.

Common Sensor Types

  • Termokuples
  • Fotodetektory
  • Senzory tlaku
  • Senzory proximity
  • Akcelerometery

Termokuples

Thermocouples are temperature sensors that consitt of two different metals joined at one end. When the junction is heated or cooled, it produces a voltage that can bee correlated to temperature. they are widely used in industrial applications due to their wide temperature range and durability.
