Industry Temperature Monitoring System 8051 Microcontroller
Many
times When temperature limits are exceeded, electronic components and circuits
may be damaged by exposure to high temperatures and Some processes work well
only within a narrow range of temperatures; So proper care must be taken is
important to monitor and protect the system.
Here
we present the Industry Temperature monitoring system. and it monitor
temperature using DS18b20 temperature sensor in these we set temperature limit
in minimum and maximum and if temperature go above or below than the limit it
stop the working of system until temperature will reaches under the limit.
Block
diagram:-
In
the system we use DS18b20 temperature sensor interfaced to the AT89S52 microcontroller.
The microcontroller is also in turn connected to an LCD screen.
When
temperature rises beyond or go below a certain limit DS18b20 temperature sensor
sends a signal to the microcontroller then microcontroller processes the signal
to the load and displays the temperature status on LCD screen. Its switch off
the load and system stop working until the temperature reach the limits.
