基于STM32单片机的热量表低成本测温电路设计
资料介绍
使用常见的电阻、电容器件,根据RC充放电原理,利用STM32单片机内置的16位定时器测量RC充电时间,再通过时间与阻值对应关系的计算,获取测量阻值,从而实现了热量表的低成本测温.
This design uses common resistors and capacitor elements according to the RC charge-discharge principle,applying the 16-bit timer in STM32 MCU to measure charging time.The low temperature cost measurement of Heat-meter is achieved by the resistor value measured which is obtained through the calculation of the matching relationship between charging time and resistor value.
