Microcontroller-based overheat detector using the temperature sensor with buzzer indication has applications in various areas including industrial application, national application. The temperature sensor is used to detect the overheating condition. The temperature sensor output is given to the comparator. And the output of the comparator IC is given to the microcontroller 89s51. LCD - The LCD shows a message when the temperature crosses the threshold level. And a buzzer is also turned on to give an indication of overheating.
It can be understood in the following video:
