For Pass standard
, learners will design a system or device, ensuring that it adheres to
the principles and characteristics of IoT, and that standards, communication methods
and security issues are considered. They will annotate their designs using feedback from
others to identify improvements that could be made during the development stage.
For example, the design for a speed monitoring system will include two pressure sensors
to detect moving traffic between them, which may have been moved closer together
following feedback from others that would make the solution more practical.
Learners will develop a prototype using off-the-shelf hardware and suitable
programming languages, such as Python, Touch Develop, Java and C++. Their prototype
IoT device will have partial functionality to solve the intended problem and meet their
initial requirements and designs. For example, the system may record the times that the
pressure sensors were triggered but not be able to calculate the speed at which the
vehicle was travelling. They will review the implementation and describe to what extent
it meets the client’s requirements.
Overall, the evidence will be well structured with some use of appropriate technical
language (including definitions), although there may be some inaccuracies with terms
used. The design may be basic in parts and some parts of the evidence may be
considered in greater depth than others.
