Electronic sensors are widely used in our daily lives and they help us in providing useful measurements and feedback control.

They are used in many applications like Temperature control, Elevator Control, Door Controls, Fitness trackers, smoke detectors User Interface etc.

In this article, I intend to provide a list of sensors used for Human Machine Interface (HMI) , their native technology and their applications.
