Abstract：Objective Considering that the current moxibustion apparatus cannot adjust the temperature
for the real-time monitoring, which easily lead to patient burns and inadequate moxibustion curative effect,
we proposed the design of electronic moxibustion apparatus based on MSP430F149. Methods First of all, we
preset the temperature with a keyboard and get a real-time temperature with the DS18B20 temperature sensor
controlled by the MSP430 F149. Then, we compared the measured temperature with the preset temperature.
In the following, based on the comparison above, we regulated the level of the screen by manipulating
the rotation of the stepper motor. Finally, we got the closed-loop temperature control. Results Through
calculating the relative error with the relative error formula according to the actual measured moxibustion
temperature, we knew that the relative error was 1.69%, which indicating that the electronic moxibustion
apparatus could control and adjust the temperature well. Conclusion After a series of experiments, the
design has been proved to be able to monitor and control the temperature, and can reduce the risk of
burning.
