Course Introduction
January 10, 2022
Outline
- Introduction to sensors and controls
- Syllabus and schedule
- Lab introduction: Arduino, Matlab
Sensor
A sensor is a device that detects and responds to
some type of input from the physical environment;
provides a readable output signal; usually requires
calibration.
Sensor
Transducer
- Device that converts energy from one form to another.
-
Converts a signal in one form of energy to a signal in
another.
Instrumentation
Design, manufacture, and use of physical instruments for
detection, observation, measurement, automatic control,
automatic computation, communication or data processing.

System
A system can be defined as an arrangement of parts within
some boundary which work together to provide some form
of output from a specified input or input
Course objectives
