Technical Report & Lab Notes

Details on experimental setup, tested materials and tag behavior

Tag designed to be applied to bottles, both glass and plastic.
Note in fact in the videos the difference in distance of the tag applied to an inert piece of wood, and when applied to a bottle containing water.
Excellent reading distances, beyond the threshold of the datasheet, reading on the glass more constant, the plastic one is sometimes not continuous, but has had a peak reading at 10 meters!
