Hello
I am working a simple power monitor that uses an Arduino and an INA219 power monitor. The current part is pretty straight forward. However, (understandably) when I leave the the line floating, the bus and shunt voltage readings provide the supply voltage. I wanted to know what are the ways I can get over it. Currently my noob sense of electronics design suggests that connect a pull down resistor of say 10kΩ. However, that might have an effect on my current measurement. Is there a better way to get rid of the floating non-zero voltage reading?
Thanks.
