Industry Temperature Monitoring System 8051 Microcontroller

Industry Temperature monitoring system

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.
