SEN0291 Library Issue?

userHead tim.carb 2023-07-11 21:33:34 219 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.
