Abstract
this paper presents the basic operation principle, the hardware structure and software programming of the Integration of smart melting point apparatus, which composed by the microcontroller, temperature sensor, heating system, mixing system, keyboard and LCD display. After conducting repeated experiments, the results emerged: the temperature control accuracy of the instrument reach ± 0.2°C, linear temperature error is less than 0.5%. All indications comply with the national pharmacopoeia standards. With the character of simple hardware structure and scientific software algorithms, the temperature control can be achieved with low cost and high precision.
