My name is Elliott and I am working on a project that utlilizes kinetic movement and converts it into AC power. I'm having difficulty trying to figure out how im going to record and plot the data. Since the power output will me in the milliwatts. Im curious to know if this sensor node will be able to record this small of a power output.
IF so, could someone assist me in writing a program (or maybe there's a pre-written program) that I can utilize. To graph out all my data!
If i need to go further in depth let me know, I had to type this out in 2 minutes because of passing period at my highschool!
Dont want to be tardy again

Probably not, but you didn't say what the current (or voltage) is.
The datasheet shows a sensitivity of 185mV per amp for the x5B version. So, you'd probably need about 1/10th of an amp before you get useful/accurate readings. (And, you'd want to use the Arduino's optional 1.1V ADC reference or provide your own reference, instead of the 5V default.)
The Hall-effect device measures current. Power (mW) is the product of Voltage x Current... So, if the voltage is low enough, you might have enough current to measure in the milliwatt range.
If you're talking about 120V or 220V power, you won't have enough current to measure (with that device) at only a few milliwatts.
Is current what you want to measure? Do you also need to measure voltage and/or power?
