reading through the forum, this sensor seems to cause a fair number of people problems, mine doesn’t seem have been discussed though. I’m fine with the fact that it jumps around a bit, being a hall sensor i was expecting it. my issue is that it drifts over time, and while some have posted they have that issue over minutes, mine drifts over days. i have a little over 5 days uptime on it right now and it has drifted up around 0.2A. when i have my laptop plugged into the arduino the readings go back to normal (and even ready about 0.1A lower then when its not plugged in. Given that, I though i probably need a pull down somewhere, but that doesn’t appear to be an issue with the module. The only other solutions I have found is to buy a another set of sensors (i have 3 hooked up) from a different batch or supplier.
