测试了LM35温度传感器良好的线性温度特性,特别是在30℃～60℃范围内,其温度特性的线性非常理想,这就为制作体温计提供了理论依据.本系统采用常规的腋下测量方式,采用常见的A/D转换芯片和89C51单片机,具有成本低,精度高,稳定性好等特点.

In this paper, LM35 tempeture sensor is tested and shows good linear characteristics between 30℃ and 60℃, which provides a theoretical basis for making digital thermometer. A/D converting chip and 89c51 single chip microprocessor are employed in this digital body thermometer based on LM35. It possesses such advantages as low cost, ...
