Welcome to the Sensors!

Types

There are a lot of different sensor types, all with their own applications, characteristics and construction. In the process of modern industrial production especially the automation ,various sensors are used to monitor and control the various parameters in the production process, like the temperature sensor, wheel speed sensor, knock sensor, pressure sensors, etc., to make devices work in a normal or optimal state then make the products to achieve the best quality.

Fundamentals

In the broadest definition, a sensor is a device, module, machine, or subsystem whose purpose is to detect events or changes in its environment and send the information to other electronics, frequently a computer processor. A sensor is always used with other electronics.

It is a detecting device that can sense the measured information and can transform the sensed information into an electrical signal or other required form of information output to meet the information, in order to meet the requirements of information transmission, processing, storage, display, recording and control.

Applications

Sensors are used in a wide variety of applications which are described on Apogee. This category contains pages explaining various sensor applications.
