Introduction to Sensors and Transducers Notes

For an electronic circuit or system to perform any useful task or function, it must be ready to communicate with the “real world” whether this is often by reading input from an ON/OFF switch or by activating some output device to illuminate one light. The word Transducer is actually a common term used for both Sensors which can be used to sense a wide variety of energy forms such as electrical signals, radiant energy, movement, magnetic energy or thermal energy etc. Devices which perform some Input function are commonly called Sensors because they sense a real physical change in some characteristic that changes in response to some excitation, like the switching on and off of a switch that changes the outcome of the light.

Sensors and Transducers Curriculum

This subject is exceptionally lengthy, and it includes almost every concept in electrical engineering because it contributes to some a part of it so for college kids to understand what to review and what to not study is very crucial. After all, we do not want them wasting their preparation time on concepts that won’t be included in their test. A curriculum is the most crucial part of students’ preparation process because it provides a structure or a format for them to hide the varied topics within the subject. Therefore, it’s vital that the curriculum starts from the essential concepts to hide all the relevant topics. The subsequent is an updated curriculum that’s set by experts within the field.

FAQs on Sensors and transducers Notes

Question 1
What are the two types of feedback loops?

Answer:
The two types of feedback loop are

  1. Positive feedback loop
  2. Negative feedback loop.

“The feedback is said to be negative/positive feedback is fedhe signal; which is feedback, subtracts/adds from the input value. It is required to control a system. The control elements decide what action to take when it receives an error signal.”
