Application of Sensors in Mechatronics

Learn about the practical principles and implementation of vital sensors in mechatronics with this free online course.

Publisher: NPTEL
Sensors are a key part of a mechatronics system. Without sensors, mechatronic systems wouldn't measure useful parameters such as temperature needed in the operation of some systems. This course discusses the critical sensors used in mechatronic systems and the terminologies required to understand the performance of sensors. You will learn about the working principles of these sensors and how to implement them in mechatronic systems.

When you look at mechatronics systems such as robotic vacuum cleaners, you realise it doesn't need any human control to do its cleaning. It has proximity and other sensors that help automate cleaning and prevent it from hitting obstacles as it cleans the house. Do you think the vacuum cleaner would control itself and perform the cleaning efficiently without the sensors? Certainly not! Mechatronic systems require sensors to measure and monitor various parameters to perform their function efficiently. So, it is essential that anyone who looks to be skilled in mechatronics systems gain knowledge of the working principles of these sensors. This course aims to enlighten you on the working principles and application of the significant sensors used in mechatronics. Before getting into the various sensors, you will learn about the different terminologies used in defining the performance of sensors. In addition, you will appreciate the comparison between sensors and transducers.

An engineer must consider certain factors to select suitable sensors for a mechatronics system project. This course will explain the factors to consider when choosing suitable sensors for your mechatronics system. It will introduce you to the various sensors for measuring displacement, position, and proximity. First, you will be shown the working principles of potentiometers and strain gauges and their application in mechatronic systems. You will study how capacitive elements and Linear Variable Differential Transformers measure displacements. In addition, you learn how encoders measure both linear and angular displacements. The course also explains how capacitive proximity and pneumatic sensors operate and how varieties of switches can act as sensors in a mechatronics system. You will learn about the working principles of hall effect sensors and tachogenerators and their importance in mechatronic systems. Next, it will be reviewed how piezoelectric sensors and tactile sensors are used to measure pressure. Also, you will examine sensors used in measuring fluid flow. The course discusses acceleration and vibration measurement. You will discover how to analyse the frequency response of an accelerometer, including the differences between accelerometers and vibrometers. The course concludes by explaining how microelectromechanical devices work and their application in mechatronic systems.

To be a sought-after mechatronics expert, you must understand how various sensors work. Without sensors, mechatronic systems wouldn't be as autonomous as you see them today. When you recognise how sensors work, you will implement them properly in your mechatronics project. It shouldn't be a surprise to you that sensors are so important. After all, sensors can replace human controls and allow mechatronics systems to perform their function independently. For example, with autonomous washers, you wouldn't need to keep checking the washer to see whether the clothes are washed. Also, with autonomous vehicles, you wouldn't need to drive cars yourself. This is why there are sensors properly put in place to help in doing the job for you. This course is designed to show you how various sensors can make your mechatronics designs very efficient and autonomous. Wouldn't you want to know how these sensors work? Begin this course today and gain the knowledge needed in developing mechatronic systems that control themselves.
