So what is a Smart Environment?

• Cook and Das define Smart Environments as
“a small world where different kinds of smart device are continuously working to make inhabitants' lives more comfortable.”
• Related to Ubiquitous Computing
”… a physical world that is richly and invisibly interwoven with sensors, actuators, displays, and computational elements, embedded seamlessly in the everyday objects of our lives, and connected through a continuous network.” (Mark Weiser et. al)
Smart Environment and Smart Devices
• Small devices that
– are connected to other devices via network protocols
– operate autonomously
– interact with
• physical world (e.g., via sensors)• humans• each other

Smart devices and Internet of Things
7
The Internet of Things(IoT) is the network of physical objects that contain embedded technology to communicate and sense or interact with their internal states or the external environment.
Scenario: The Smart Printer Environment
• Requirement for an adequate environment for Digital colour printers from the imagePRESS family
• Challenge to build a smart system for monitoring environmental conditions, such as
– temperature
– humidity
– lighting
• Based on the monitored data systemcan adapt the lighting conditions or signal the current situation in the room

Assignment
• The team will use embedded devices as the Raspberry Pi connected to environmental sensors to capture environmental data.
• The embedded devices will communicate with each other using specific IoT protocols, e.g. MQTT.
• A controlling instance will process the data and react accordingly to specified rules (possibly configurable through a web interface).
• Philips Hue light bulbs will be used to provide awareness of environmental conditions in the printer room or to adapt lightning conditions inside the room.
