This works well.
This module worked well compared to another I purchased from Adafruit. The Adafruit module was DOA and I ended up throwing away 3 units. I couldn't get customer support because no one at the company knew anything.

Can detect current
I use it to detect when the sump pump switches on and off - draws current or not. Works with both 3.3 and 5 volt supply - the data sheets confirm this. Took me some time fiddling with the potentiometer to get it how I wanted it. And still I couldn't get the digital output to a proper "1" level. So I wired it to the analog input of my ESP8266, and was able to detect current reliably that way. Didn't bother with the analog output of the device (AOUT) at all.

Really noisy current sensor.
Cheap? You bet. Will it take a LOT of averaging to get a good signal? You bet.
