I and probably a lotta other people have a chronic problem that is in
need of a simple solution. We're about to move into a new bldg and I
have to do a lotta install'ns of PCs, etc., so I'm under the desk a lot.
Every room in the new bldg has the motion sensors that turn off the
lights after a few minutrd, and I have to continually get up and wave my
arms to reactivate the sensors.
Some of the sensors are PIR motion detectors, and some are ultrasonic.
The US ones could be fooled with a fan in front of the sensor, But how
can I fool a PIR motion sensor? I have to have a warm, moving body in
front of the sensor, maybe a caged animal? Or a long wave IR generator
that moves or generates an intermittent output. I've ruled out candles
or other flames for safety reasons. A friend suggested a Lavalamp might
work, but I don't think I want to wait ten or twenty minutes to warm it
up. Maybe one of those old lamps with the rotating picture and fan
blades on top, that turns by convection currents from the light bulb
heat. I know that the IR output from IR LEDs is much too short a
wavelenght. Any ideas? Thanks.
What about strapping a Gerbil to the fan? Works for both types of
sensors
