This block diagram explains on how the project function. Form the temperature sensors, it will detect the temperature and Wheatstone bridge function as to convert the resistance to voltage then the Op-amp to amplifier the voltage. From the Op-amp it will transfer to the Arduino for process the data. The result of the data then will be display on the LCD and transfer via IoT. If the device detects abnormal condition the buzzer act as alarm will ringing.
