SEN0291 Library Issue?
tim.carb 2023-07-11 21:33:34 193 Views1 Replies I'm using the Arduino and Raspberry Pi code from: https://github.com/DFRobot/DFRobot_INA219
Using a 24 vdc power supply the SEN0291 always reports a negative BusVoltage. E.g. BusVoltage: -8.14V
Other ina291 libraries report the correct BusVoltage as does a DMM.
Thanks for the help.

Make sure that your sensor is properly calibrated. Also, make sure that your power supply is not fluctuating.
