Abstract
The temperature acquisition display and alarm system is used a need for
precise temperature control of the alarm system to achieve accurate temperature
acquisition of the more limited display and sound and light alarm function. With
convenient system users to better understand the current temperature security
situation,it make corresponding regional sites safety guaranteed.
The
system
uses
AT89C52-SCM
as
Microprogrammed
Control
Unit
and
adopts digital temperature sensor DS18B20 as the temperature component. The
temperature sensor DS18B20
collects temperature signals and sends them to
SCM for dealing with, then SCM transfers the processed temperature data to LED
for dispalying which can realize the fast and accurate temperature measurement
function and the more limited sound and light alarm function. This thesis has
