The system has an expected lifespan of three years, limited by the lead-
acid battery. All other components are solid-state and, bar corrosion or
mechanical degradation, will be obsolete before they fail. Replacement of the
standby battery will thus enable operation well beyond the design lifetime,
should this become necessary.
The cost for low-volume production is expected to be in the order of
ZAR2500 per system, which is les s than one tenth the cost of the existing
solution. Furthermore, this replacement has many benefits over the original
system, including automatic data delivery and fully autonomous operation.
We thus conclude that the project’s objectives have all been met and that
all challenges have been overcome.
