Hi. I'm having the same issue. One thing i have noticed is i'm using a step uppower supply from 3.3v to 12v. Once i connect the + lead in to the  SEN0262 i start registering current even tho the - lead is unconnected. I think the current it looping back through the ESP32 to the common power supply. Is there a way to stop this or filter it out?

 

I have a SEN0262 connected to the 16-Bit ADC connected to the ESP32. If i remove the + lead the sensor drops back to 0v 0ma as expected. 

 

Thanks

Andrew
