I mean if ACS 712 outputs the analog voltage, then why am I getting digital readings on the serial monitor?
how to develope a formula which can convert those voltage readings into current ?
I am assuming that I will have to call that map function in MS excel and not in Arduino IDE.
The digital readings on the serial monitor vary from around 480 to 1023 for motor speed of 50 rpm.
where did u get the power factor thing into this
if I increase the Vref to 5v by rotating the Vref pot on ACS 712 at its max position and making the gain maximum, I constantly get the value 1023. No fluctuation. (which really does not make sense.) If I set this pot to minthe values are again constantly zeroes.(catches my nerves..!!!)
Now, If I am correct, these values are representing the voltage and not the current since, the output of the ACS712 is analog voltage.
R u saying that current will increase as this Digital number increases and I will have to find the relation between them.
If I have to find the relation and evetually measure the values from DMM for the current, I wonder why they call it as a current sensor.
