Shown above is my 1982/3 senior project. It consisted of
four thermistors (used to measure heat),
four 115VAC relays (controlled by +5VDC), three LEDs, a smoke detector, a +5VDC
power supply
and an embedded controller (developed from scratch).
Today, typical access control systems integrate in a number of
sensors and controls (including
smoke and fire). As the PIV cards are deployed along with the access
controls systems, its
good to have expertise that can address technology issues at any level.
