    Hello,

    Does anyone know, for an advanced amateur, the cheapest (but quality of
    course) evaluation kit for very low cost RF Transceivers. I plan to
    "sensor" my house so I need to base station and least 20 "remote" stations.

    Thanks in advance for any responses,

    Larry

    ** Kinda, slightly interesting to know if your " sensors " are simple
    on/of switches or maybe hi-res colour video cameras.

    Might affect whether you idea is doable or insane.

    What kind of data will you be sending over the air - a few bits,
    serial data stream, video, etc.?
    What is your definition of very low cost? There was a guy a few weeks
    ago on comp.robotics.misc who wanted to control a stepper motor with
    low cost. When someone suggested a $15 stepper motor controller, he
    said thanks but it was too expensive for him. Oh, brother!

    Hi Guys,

    Thanx.
    I will be sensing just voltages so I will be transmitting/receiving one to
    no more than 15 bits.
    I hope to keep the average cost per station below $25 and the cost of the
    whole mess below
    $600.

    Thanks again!
    Larry

    Given that you could do it with a $2 microcontroller and some discretes I can see
    his point.

    I am also doing something similar and I don't want to deal with
    discretes, so I ended up opting for Maxstream Xbee modules. They are
    cheap ($19) and they are high quality. They work on the Zigbee
    standard and mesh networking is possible.
