CM11A & Temp. Sensors

Finally won an ebay auction on a CM11A, for a 2-way X10 device to hook up to HAL.. Now to wait for it to arrive, and hope its in working condition.

Also ordered me a pack of DS18S20 digital temperature sensors, so I can play with hooking them up to a serial port. Hoping to monitor at least 4 zones with these bad boys, assuming I can remember enough or refresh my memory on basic electronics. Plan to monitor outside, basement, attic and main floor with these. Would like to do more zones than that, but I’ll have to learn how to do more than the 4 shown in an article.
