Interface: Gravity Analog (PH2.0-3P，analog voltage output 0.2-2.8VDC)
I do not see the .2 offset when there is 0 current flowing. I see close to 0 volts. I'm using a 3.3v power source.
Is the Doc wrong or do I have a bad board or ?
Hi Jdavis22! It sounds like you’re facing an interesting issue with the SEN0211 sensor. It’s crucial to ensure that your connections and power supply are solid. Sometimes, offset discrepancies can occur due to calibration. If you're looking for different ways to handle those voltage variations in projects, you might want to check out something like Block Blast for inspiration. Hope you find a solution soon!
