Introduction
With advances in technology, there is a constant demand for improvement in standard
of living, security and energy efficiency. Every building be it residential, commercial
or industrial runs on some or the other form of energy, thus there is a need to reduce
and optimize this energy consumption. Efficient energy management not only reduces
consumption but also reduces energy costs.
Scientech 6205SB IoT Enabled Smart Building training setup is specially designed to
help understand the concept of smart buildings and how various sensors can be
deployed and their data can be used to generate events and trigger alarms. Scientech
smart building comes with various sensors. The data from these sensors can be used

1. Smart Touch Panel:
The built-in touch switch panel in Smart Building is programmed to enable easy
user control .It provides the user accessibility and control over various devices
such as lights etc.
This panel can be used to change state of lights in rooms of the smart building
and can also be used to control analog devices such as fans (speed), the output
of which can be seen as a function of intensity of light of the bulb connected to
the bulb holder of the Smart Building.

2. RFID module:
RFID module is generally used for access control in smart building. Passive
RFID tags are used for communication with the RFID reader. The tags are read
and if their ids match with the ids stored in the database; access is provided.
RFID modules are therefore important from security and access control point of
view.
3. Bulb Holder:
Scientech 6205SB comes with a built-in bulb holder. A bulb connected onto this

affects the intensity of light of the bulb. This variation in the intensity of
brightness of bulb can be easily linked to variation of fan speed which is
controlled using a regulator.
