The temperature sensor is used in a computer, refrigerator, automobile, medical device, cooking appliances, electrical motor, etc. There are several types of temperature sensor used.

Temperature sensor uses to detect the temperature and heat energy and convert it into an electrical signal (in form of voltage or current). Such as,Įach category is having the different types of sensor as follows. Sensors are split up into four main categories. In daily life applications, commercial and industrial devices, the educational projects, different types of sensor are used with a specific role. You can easily understand this from following simple block diagram.įor example, in an automation system, the sensor is the most important equipment that provides an input to the programmable logic controller (PLC). The main function of the sensor is to identify and communicate with physical quantities such as temperature, heat, pressure, distance, moisture, gas, and so on.Īnd it provides output in the form of electrical signal to connected control systems. In other words, a sensor is an electronic device that can transform energy from one form to another form.

In general, sensor is known as a Detector.Ī sensor is an electronic equipment that is used to detect and observe the physical activities and pass the notifcation/signal to other electrical control devices.
