In this design, the temperature-collecting system is composed of 8 bit singlechip and 16 bit A/D converter based on actual requirement. It can still improve the performance price rate of the system in comparison with using 16 bit singlechip.

• 在本设计中，根据实际需要，采用8位单片机和16位A/D变换器相组合构成温度采集系统，较之采用16位单片机，可进一步提高系统的性价比。
