Pressure Sensor

It measures the pressure applied on any surface. It works on the principle of like piezoelectric, resistive and capacitive. When the pressure is applied, it is converted into the electrical signals.

Pressure Sensor

It finds its application in variety of industry like aerospace, automotive, etc. Accuracy and reliability are important characteristics of pressure sensors as they are frequently relied upon to measure accuracy and safety in many applications. The ability to measure altitude can improve performance, efficiency and safety in many applications.

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.
