摘　　要：将温度传感器采集得到的信号经A/D转换器转换,然后送往单片机进行处理从而得到相应的温度值是目前温度检测的常用方法。本设计一改传统的设计模式,利用单片机P1口的电路特殊性,设计出一种温度检测装置,并对此进行了误差分析。此电路设计结构简单,测量精度较高,有很强的实际应用价值。The common method of temperature measurement is capturing the signal by A / D converter and then is processed by Single-chip. The design Changes the traditional design pattern, which uses A / D converter to measure. It uses P1 to capture the signal and then temperature is got through calculation by Single-chip. It is showed that the design is reasonable through error analysis. This design circuit is simple, measurement precision is high and the practical application is strong value.
