Abstract:
Objective To design a new kind of wireless monitoring thermometer which can help the doctor to monitor the patient's temperature without touching them. Methods The system is based on a new kind of single chip MSP430F413,the thermistor was used in temperature detect part; the single chip's comparator A and timer A was used in A/D converter part to realize slop A/D; the NRF2401 chip was used in wireless transmission part; the system is connected with PC in the way of serial communications. Results The thermometer can work in -40 to 85 ℃ when the temperature is near animal heat,the thermometer is most accurate which precision is 0.1 ℃. Conclusion The system can measure the patient's temperature accurately,at the same time,the temperature data is sent to the receiving end in the way of wireless communication,and then data is sent to PC,which PC can record the temperature curve data and help the doctors to diagnose.
