Sunlight Triggers Motion Sensor

I live where it's gray much of the year. My ring doorbell motion sensor works great in the winter, only triggering when someone actually approaches the door. In the summer, all bets are off. This is one of our first warm, sunny days and the sensor has been triggering every 4-6 minutes. What can I do to fix this issue? I already have motion zones set up, and like I said, it works great on a cooler, cloudy day.
