DEFINITION OF UNDERSTAND EMBEDDED SYSTEM
© 2016 Software AG. All rights reserved. For internal use only
 An embedded system is a dedicated
computer system designed for one or two
specific functions.
 This system is embedded as a part of a
complete device system that includes
hardware, such as electrical and
mechanical components.
 The embedded system is unlike the
general-purpose computer, which is
engineered to manage a wide range of
processing tasks.

WHAT IS A SENSOR?
© 2016 Software AG. All rights reserved. For internal use only
A DEVICE THAT DETECTS THE CHANGES IN ELECTRICAL OR PHYSICAL OR OTHER QUANTITIES AND THEREBY PRODUCES AN
OUTPUT AS AN ACKNOWLEDGEMENT OF CHANGE IN THE QUANTITY IS CALLED AS A SENSOR. GENERALLY, THIS SENSOR OUTPUT
WILL BE IN THE FORM OF ELECTRICAL OR OPTICAL SIGNAL.
 Pressure sensor
 Ultrasonic sensor
 Humidity sensor
 Gas sensor
 PIR motion sensor
 Acceleration sensor

GATEWAY
• An IoT Gateway provides the means to
bridge the gap between devices in the field
(factory floor, home, etc.).
• The Cloud, where data is collected, stored
and manipulated by enterprise
applications, and the user equipment.
