- All I can think of is the Smart Temperature Sensor, SMT 160-30, brought
- on the market by Smartech BV, Breda, The Netherlands (one or two dollars
- I guess). The sensor provides a dutycycle modulated signal which can be
- processed by a simple processor or a computer. The absolute accuracy amounts
- to .5 degrees Celsius in the range from -30 to +100 degrees (C) and 1 degree
- from -45 to +130 degrees (C). The resolution is in the order of 1 milli-degree

- Hope this helps. Best 73's
