摘要
NTC热敏电阻是一种负温度系数的温度传感器,并在测温系统中广泛应用。该系统以STM32F103ZET6微控制器为核心,通过热敏电阻分压来测量系统的温度,具有精度高、分辨率高、体积小、响应速度快、成本低、功耗低等特点,数据处理基于对热敏电阻测温曲线的分段线性化、分段线性插值处理,提高了测量精度。所设计的测温模块对-50℃~100℃范围内的温度进行了实测,效果良好。
NTC Thermistor is a kind of negative temperature coefficient of temperature sensor,and it is widely used in the temperature measurement system.This system uses the stm32 Microcontroller as the core.Through the thermistor partial pressure to measure the temperature of the system has some features,such as very short time,low cost,low power dissipation and so on.Data processing based on piecewise linearization of thermistor temperature curve and piecewise liner interpolation,the measuring precision is improved.Design of temperature measurement module of temperature in the range of-50℃~100℃are measured and the effect is very good.
