## Customer Reviews

### ⭐⭐⭐⭐⭐ This works well.
*by R***A on February 17, 2025*

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
*by T***V on December 1, 2023*

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.
*by W***L on June 25, 2023*

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