/*

  Library for TSIC digital Temperature Sensor Type 206/306 and may more.

  using ZACwire™ Communication Protocol for the TSic™

  Manufatorer:    IST AG, Hygrosens, ZMD

  Original Code:  http://www.mikrocontroller.net/topic/82087

  rewritten by:    Rolf W.

  Date:        2010.03.06

  Temperature-sensor uses 2 Pins, one for VCC and the second for Signal (= ZACwire Protocol).

  With call of the Function ".....getTSicTemp();" the Senor will get power measure and will be turned OFF.

  In that case it uses only energy while measuring. There is another method with Interrupts, measuring

  at an constant rate, which is not implemented jet.
