Motion Sensor triggering alarm while I’m in my home alone

This evening, I set my Ring system to Home and I walked past the motion detector (from the living room to the kitchen) and it triggered my alarm. This has never happened before. In the past, I’ve been at home all day with the alarm set to home while I moved throughout my home, and the alarm never triggered. My concern is that I’ll get up in middle of the night and trigger the alarm accidentally. What’s the best way to resolve this?
