1 year timer for furnace filters ( beyond reasonable)
Archiver
Posts: 46,084
Since CFM monitoring is much more high tech than most do on this
list, monitoring motor amps is a fair approach. if the belt breaks,
the amps will change. The blower wheel undoubtely had 'forward
curved' fan blades. these use more power as they move more air, but
offer resistance to the motor.
Also. motor hours will offer a decent reflection of furnace use, but
not humidifier use. for that you need to monitor gallons of water.
This is easier still, the solenoid on the humidifier will be on or
off. just tie in to that signal.
A better unit would monitor humidity of the heated air, and also
humidity after the humidifier air was fully mixed with the air
stream. a dirty filter would have a lower RH as it would not
transfer moisture as effectivly.
A still better unit would monitor total water useage. in my
experiance, it is the particulate in the water that clogs the filter
and not any airborne particulate.
and Rodent, a slightly more simple calender monitoring would be to
use a sensor to monitor the tides. the higher pull from the moons
proximity occurs daily and a sensor would not be effected by either
weather or eclipses. I am not sure how this would be effecte by
leap years.
and still another feature would be to monitor the lenght of the days
and nights. the spring and autum equnoxes have equal days and
nights. the Sumer and winter solstace have the longest day and
longest night respectivly. even if weather was bad, you could
program to monitor the days to pin point those 4 days, even by
monitoring the days preceeding and following and comparing day
lenghts.

The water is purified through RO and pH balanced, the filter/evap pad are
changed annually to prevent excessive bacterial growth.
I considered an impellor flow meter, but the bacterial growth is more of an
atmospheric exposure factor.
So far my best guess is to use a serial RTC like the DS1305, has anyone had
experience with these animals ?
You guys are great, I really enjoyed the replies.
A coworker suggested an organo-geek solution:- Grow wheatgrass that
interrupts a laser at a predetermined height above the grass based on growth
tables for a year ;-)

I love it, but now you're back to all sorts of environmental sensors, as
growth will vary according to amount of light, temperature, moisture in
the soil, etc (unless of course you grow it hydroponically, which means
you're liable to attract the attention of your friendly local law
enforcement folks... ;-)
Maybe what you can do is some sort of differential circuit arrangement,
in which you have two crops, one in your furnance and one in the open to
act as a control. This would give you a sort of organic OpAmp circuit -
what would matter here is not the specific height, but the difference
between the two crop heights, which in turn would indicate internal
furnace state.
And if you can build an organic opamp, this would seem to open the field
to a whole variety of organic computing elements. Kudos to the first
organic FlipFlop, and if you build an adder you can have that counter
that kicked this thread off.
And finally, imagine the first Turing-complete garden. Yes, you grow it,
then try to get it to past the Turing test...

If you used Kentucky Bluegrass it reaches an average height of about
8 inches and spreads out.
Zoysia reaches a height of about 4 inches although seed stems extend
to almost 12 inches.
Saw Palmetto extend over 5 feet for the blades and over 8 feet for
the seed stems.
Bamboo tops 16 feet.
Did he offer any tech data sheets on cailbartion ?
seems that matching the 66% of maximum groth would put the sensor in
the sweet spot for sensitivity. and higher resoultion would be had
by higher growing varieties.
Puts new meaning in the concept of cross-polinating scientific fields.

yet.
