A wet sensor. It’s hard to tell if this is condensation, sideways rain, or drips from above, but this is where we learn the value of IP55 rated boxes.  Sensor v3 will have a weatherproof enclosure (see IP code system) and also a weatherproof ultrasonic rangefinder. Luckily it seems sensor v2’s electronic hardware is still working after this soaking.
