Hi, I want to measure the voltage of the fan regulator and feed into ADC pin of ESP 8266, The range of ADC is 0 to 1V, theoretically I can use the below circuit. VG1 being the load voltage taken from the fan regulator, VF1 will be driven into my ADC pin , My doubt is, can i go with this circuit or is there a better way to convert 0 to 240V to 0 to 1V? please provide me insights.
Here I have considered peak voltage(340) not rms.
