本模块基于电阻分压器原理设计,使接口端输入电压降低5倍,Arduino模拟输入电压高达5V,那么电压检测模块的输入电压不能大于5V × 5 = 25V (如果采用3.3V系统,输入电压不能超过3.3vx5 = 16.5V)。因为Arduino AVR芯片用于10 AD,所以模拟模块的分辨率为0.00489V (5V / 1023),因此,电压检测模块检测的最小输入电压为...

The constantvccrepresents the supply voltage (5.0V),adcMaxis the maximum value of the analog-to-digital converter (1023), andsensis the sensitivity of the ACS712 sensor (185 for 5A). Note that sens = 185 instead of 0.185. Again, if you have a ACS712 sensor for a different current range...
VRL = analogRead(MQ_sensor)*(5.0/1023.0); //Measure the voltage drop and convert to 0-5V 现在,计算了VRL的值,您可以使用上面讨论的公式来计算Rs的值以及比率(Rs / Ro) ratio = Rs/Ro; // find ratio Rs/Ro 最后,我们可以使用对数公式计算 PPM,并将其显示在我们的串行监视器上,如下所示 ...
