Abstract
This design spread with new arithmetic figure to sensor to
constitute the temperature to measure and control for core
with the machine of slice system. Single slice of the
system's ATMEL AT89S52 of INTEL MCS-51 instruction of
adoption of this system machine conduct and actions
MICROARRAY , complete the temperature worth receive,
conversion, report to the police to handle; New and single
road string produced by DALLAS line the arithmetic figure
temperature sensor DS18B20, and complete the
temperature to measure, analysis, judgment the worth,
output function. Then the computer controls an electric fan
or a heating wire to keep the temperature within a certain
range.
