谢谢Piston!
比如我只在标签上看到如下例:
Channel: 238,
Serial Number: 39101300237,
Wafer Number: 01191B08,
MRP Number: 8447307,
Calculated Values at 5V,
Vout @0%RH: 0.819319V,
Vout @75.3%RH: 3.235373V,
Accuracy @25C 3.5%RH,
Zero Offset: 0.819319V,
Slope: 32.085708 mV/%RH,
Sensor RH: (Vout-0.819)/0.032,
Ratiometric Response,
For 0 to 100%RH,
Vout = Vsupply (0.164 To 0.806)。
在网上搜索到的资料上有:
电压输出(一次拟合曲线) V = V[0.0062(传感器RH) + 0.16], 25℃环境条件下,
温度补偿:真实RH = (传感器RH) / (1.0546 - 0.00216T), T单位为℃
但不与我上面说的公式一样。请赐教!!!
