plant care

I'd like to use a stamp to water my plants and possibly eventually light
them. but right now, just water them. so i figure i need some kind of
moisture sensor for each plant and then some device to turn water on and off.
I suspect I'd put the water in a resevoir of some sort so I don't need to
plumb pipes to my garden.

has anyone done anything like that? or thought about it?

thanks

bob

    What you need is called a "soil moisture sensor." They usually go
    for about $50.00 each, but can be as much as $300.00. One should
    work with a basic stamp; although, depending on the current, you may
    want to run it through an opamp.

    I would not get into all the plumbing; frankly, you can get modular
    soaker hose setups from any hardware or garden store. Running the
    solid black hose through a wall or something would be really simple.
    There are even hooks one could use to make them more aesthetically
    pleasing.

    Good Luck!

    Radio Shack used to sell a cheap analog soil moisture meter. They were $20
    or so and may be adapted with an ADC.

    The cheapy drip irrigation stuff would probably work well for plumbing.

    Hi Bob,


    You might take a look at
    http://www.emesys.com/OL2mhos.htm
    http://www.emesys.com/smx.htm

    Those show interface from the Stamp to soil moisture sensors. You
    can put stainless steel or carbon probes right in the soil, and then
    observe what electrical signal corresponds to "dry" as you define it
    for your plants. For better results, people favor embedding the
    conductivity probes in a plaster of paris block. Bury the whole
    block. The moisture in the block comes into equilibrium with the
    moisture in the soil, and the block acts as a buffer against the
    salts and other stuff that affects the conductivity of your
    irrigation water. Things like the Watermark sensors are developments
    of that principle. There are other kinds of soil moisture monitors
    you can find at the http://www.sowacs.com web site.

    Ditto. I use drip irrigation stuff in the yard.

    http://www.onestopgardens.com/osg/taf/displayitem_os.taf?
    Itemnumber=46095

    It connects to the house hose connection via a standard automatic
    sprinkler valve (about $20.00 from home Depot) 24 VAC to power the
    valve on and off.

    I made points with the wifie by 'dripping' her Fushias daily. Those
    plants want to live in a swamp (so she says) so I flood the pots
    daily per instructions.

    For the tomatoes, I water every other day and skip rain days and one
    day after it rains.

    Her roses get water every 3 days or 2 days after a rain.

    I thought about a moisture sensor, but so far this has worked well
    enough to be satisfied.

    A note about tubing, you can use garden hose with the fittings so you
    don't have to buy more expensive special tubing. And Wal-Mart sells
    some limited parts.
