Ah Idea to improve the sensitivity when using
movement detectors to operate lights around the house and help overcome the
latency problem.
The Dual Tech movement detectors we use at
work are
very sensitive on the microwave section, when setting up a jumper is used
to
link the LED to either the microwave or PIR sections, when setup is
finished this is moved to the normal position indicating an alarm
condition.
Connecting to the jumper pin used for the microwave setup would provide a
very
sensitive output for motion, it should be possible to interface this
directly
with a HV input port switching low on detection. This may also overcome the
problem a few people have had with interfacing HV to their alarm system
without
using relays.
Just an idea.
