I upgraded my Dakota sensors in February to a new type half the size with 15X better coverage.
My lesson? Be careful what you wish for.
The new sensors ARE more sensitive, cover MUCH more area and I spent weeks wringing out false positives from squirrels, bumblebees, birds, leaves, etc. My most elusive issue was moving shadows on a glass surface triggered a heat delta on sunny days. I have it 95% resolved now, though.
I also upgraded my original solar lights (original charge was too low, only 2 to 3 minutes of light). The new lights were $8 instead of $6, but three times the solar cell area, twice the battery storage and slightly larger. A big benefit is that they work 24/7, regardless of power outages.
Old lighting compared to new lighting. Not a fair comparison as positions are different and there is an extra light but the new lights also distribute light better:
