Onset, a world leader in data loggers, has published a case study on how the Hunter Museum of American Art uses Onset HOBO® MX1101 data loggers to maintain optimal climate conditions in its galleries. The Bluetooth Low Energy (BLE) enabled data loggers continuously measure and record temperature and relative humidity (RH) levels, providing the real-time and historical data needed to protect exhibits.

Located in Chattanooga, TN, the Hunter Museum of American Art features an extensive and diverse collection of American art created with a variety of different materials, including paintings, sculpture, photography, mixed media, furniture, works on paper, and contemporary studio glass. To preserve this artwork, the museum needs to maintain a stable interior climate for each of its three buildings, closely controlling temperature, relative humidity and other unfavorable environmental conditions to prevent harm or the deterioration of objects.

The Onset case study examines how the museum’s registrars replaced traditional environmental loggers with Onset’s BLE data loggers to eliminate the time and costs associated with manually collecting data. It also discusses how registrars can easily download temperature and RH data wirelessly from the Bluetooth-enabled loggers—located up to 100 feet away—on their smartphones or tablets using Onset’s accompanying HOBOmobile® app.

Streamlined data collection and reporting
“The museum is comprised of three different buildings, all interconnected and each with its own climate-control needs,” said Elizabeth Le, registrar at the Hunter Museum of American Art. “The Bluetooth data loggers and mobile app make access to the data very straightforward and convenient. I can retrieve the data I need instantly from each HOBO location using my iPad.”

“We have to keep every data record and monitor any extreme changes. If there's a paper buckle or a ripple, we can narrow down the cause with the assistance of the HOBO,” said Theresa Slowikowski, registrar at the Hunter Museum of American Art. “The HOBOs are such an advancement and an important tool for us.”
