NEW YORK, NY (AP).- It will take a good eye to spot them, but dozens of tiny, very modern works of art have been installed near the 15th-century unicorn tapestries and other medieval masterpieces at a New York City museum. The Metropolitan Museum of Art is announcing Thursday that a network of wireless environmental sensors designed to prevent damage to the collection is being tested at its Cloisters branch. The IBM sensors — each housed with a radio and a microcontroller in a case about the size of a pack of cigarettes — can measure temperature, humidity, air flow, light levels, contaminants and more. They are inexpensive and run on low power, and several can be positioned in a room, scientists said Wednesday. The information collected goes into a three-dimensional “climate map”
