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. Sensors are used in everyday objects such as touch-sensitive elevator buttons tactile sensor and lamps which dim or brighten by touching the base, besides innumerable applications of which most people are never aware.

Availability of real-time data and reliable transmission from the sensor to the receiver are crucial for medical, nuclear and autonomous vehicle applications. This article details how sensors meet the requirements of such applications. Sensing technology is evolving at a very fast pace with miniaturisation of microprocessors, embedded systems and other modules, especially micro-electromechanical system MEMS sensors.

Difference Between Sensors and Actuators

In this tutorial, you will learn the difference between sensor and actuator. The main difference between sensor and actuator is that actuator is a output device and sensor is a input device. First I will introduce you to actuator and then I will explain you about sensor and their types. Actuator and sensors are different parts of machinery upon which the working of machinery depends. Here we have brief introduction and the technical different between them.

Sensors and Actuators Integration in Embedded Systems

Haynes ManualsThe Haynes Author : Nathan Ida Description:This undergraduate textbook introduces students to the principles and applications of sensors and actuators, crossing multiple disciplines including aerospace, biomedical, chemical, civil, electrical and mechanical engineering. An excellent professional reference for those needing to learn the basics of sensing and actuation, this book is a good choice for industry training seminars. This book connects the dots of theory and circuits basics into meaningful systems and real-world applications. Designed to introduce students and practitioners to the principles and applications of sensors and actuators, this book discusses processing hardware and the embedded systems software that connects them. It is written based on the theory that a system is made of three components: Inputs, Outputs and Processors and looks at sensors and actuators based on the broad area of detection.

Sensors and Actuators are essential elements of the embedded systems. These are used in several real-life applications such as flight control system in an aircraft, process control systems in nuclear reactors, power plants that require to be operated on an automated control. Sensors and Actuators mainly differ by the purpose both provide, the sensor is used to monitor the changes in the environment by using measurands while the actuator is used when along with monitoring the control is also applied such as to control the physical change. These devices act as the mediator between the physical environment and the electronic system where the sensor and actuator are embedded. Basis for comparison Sensors Actuators Basic Used to measure the continuous and discrete process variables.

We live in a World of Sensors. You can find different types of Sensors in our homes, offices, cars etc. All these and many other automation tasks are possible because of Sensors. Before going in to the details of What is a Sensor, What are the Different Types of Sensors and Applications of these different types of Sensors, we will first take a look at a simple example of an automated system, which is possible because of Sensors and many other components as well.
