NTC温敏电阻温度计算

其中 B 、R25在NTC spec中可以查看到。

Rup在ADC采样电路原理图中查看

//12bit ADC
int main()
{
   /*  Write C code in this online editor and run it. */
   printf("Hello, World! \n");
	int adc = 0;
   int B = 3975;//3975K
   int R25 = 10000; //10K
   int Rup = 15000; //15K
   float Rt;
   float cacl;
 
	for(adc =0;adc < 4096;adc++)
	{
		Rt = ((adc * Rup) /(4096 - adc));
		cacl = (B*298.15/(298.15*log(Rt/R25) + B)) - 273.15;
		printf("%d   %f    %f \n",adc,Rt,cacl);
	}
	
	
	
	
   return 0;
