Temperature Sensor
It is used to measure the temperature and convert it into readable electrical signal. This sensor is used in RTDs, thermistors, and thermocouples.
A thermocouple consists of two different metals connected to one end. When heated, they produce a voltage proportional to the temperature difference between them. RTD uses temperature-dependent change of pure metal or metal. It is accurate and stable but it is costly. While a thermistor can change its resistance with the change in the temperature because it is temperature-sensitive.
Sensors in Electrical Engineering
Sensors are the detection devices of the digital world. It senses the physical change in the environment and converts the sensed data into machine-readable or understandable language. The sensors are of two types i.e., analog and digital sensors. As the name suggests, an analog sensor provides analog values which is a set of infinite values. On the other hand digital sensor converts the data into digital signals which is a set of finite values. There are various types of sensors that are being used in various fields like the automation industry, healthcare sector, and many more.
In this article, we will study sensors, types, and practical applications.
