摘　　要：数字化温度传感器可以直接将温度量以数字脉冲信号形式输出,具有测量精度高、抗干扰能力强、传输距离远、外围接口电路简单等诸多优点。同时数字温度传感器还可直接与微处理器进行接口,大大方便了传感器输出信号的处理。本文以PWM模式输出的TMP04型数字式温度传感器为例,介绍由PIC单片机实现的几种测温方案,并给出软件设计流程。Digital temperature sensor can export temperature information of digital pulsing signal,and has the advantages such as higher measurement accuracy,better ability of anti-interference,farther transmission distance and simpler peripheral interface circuit. Especially, the digital export signal can send into the microprocessor directly, it has simplified greatly the hardware interface between the sensor and the microprocessor. Taking digital temperature sensor TMP04 as an example, which export mode is PWM,we design some kinds of temperature measurement schemes which was implemented by PIC single chip, and have actualized the measurement of temperature using simple circuit and program.
