For Pass standard
, learners will describe the purpose and applications of at least four
different IoT systems and/or services from at least two different sectors. They will
explain the principles and characteristics of the IoT systems and/or services and how
they have been used. For example, an IoT heart rate monitor will transmit data via a
close-range communication method to the user via a handheld device.
Overall, the evidence will be well structured with some use
of appropriate technical
language, although there may be some inaccuracies with terms used and it may be basic
in parts. Some parts of the evidence may be considered in greater depth than others.
Learning aims B and C
For Distinction standard
, learners will evaluate the IoT system or device, using
feedback and comparison against the client’s requirements, to produce an optimised
design for the system. For example, a speed monitoring system could be optimised by
using feedback that the distance between sensors was too great, so decreasing the
distance between sensors could give more accurate readings and speed calculations.
Learners will include a comprehensive range of risks and benefits of their design. They
will include off-the-shelf hardware components and the standards, communications
requirements and control diagrams, such as flow charts, of the design while taking
security, local legal and sustainability characteristics into consideration.
They will develop their IoT system or device using off-the-shelf hardware components
and suitable programming techniques and constructs. Their system or device will be
functioning and efficient, and will meet the client’s requirements. They will reflect on
their own performance during the design and development of an
IoT system or device
and the evidence will demonstrate their effectiveness in self-management and individual
responsibility. For example, the speed monitoring system could be optimised by
reducing the sensitivity of the pressure sensors so they’re
triggered only by forces
exerted through typical travelling vehicles, reducing the number of false recordings
from pedestrian or cyclist travel.
Overall, the evidence will be easy to read and understand by a third party. It will be
logically structured, use appropriate technical language throughout and use a high
standard of written language, i.e. consistent use of correct
grammar and spelling, and
consistent reference of information sources.
