Industry Temperature Sensing With SMS Notification 8051 Based Microcontroller

Industry Temperature sensing system with GSM notifications

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 sensing system with GSM notifications 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 then it send massage to the authorized contact which is predefine number in database and also 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 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 and displays the temperature status on LCD screen and then its send the temperature status massage to the authorized contact which predefine in database through GSM.
