The industry’s first data logger that records and transmits CO₂, temperature and relative humidity data wirelessly to mobile devices via Bluetooth has been introduced by Onset. Building on the success of Onset’s award-winning HOBO MX1101 Bluetooth temperature and humidity logger, the self-contained MX1102 is suitable for indoor air quality studies and environmental monitoring in schools, hospitals, laboratories and other environments.

The data logger measures CO₂ over a range of 0-5,000 parts per million, and enables users to access the data from mobile devices within a 100-foot range. There are no cables to deal with, no computer software to install, no devices to pair, and no internet access required.

Designed for hassle-free deployment, the HOBO MX1102 features an easy-to-read LCD that displays current readings and logger status, and can run for six months on four, user-replaceable AA batteries. The logger also features an onboard USB port for users who want to configure and offload their CO₂ loggers with a computer. This port also provides the option of powering the logger via USB for applications that require more than six months of monitoring or faster logging rates.

Onset’s HOBOmobile app makes it a easy to configure HOBO MX1102 CO₂ loggers and manage the collected data. Using a mobile phone or tablet, users can view data, check the operational status of loggers, share data files and graph images for analysis in Excel, Numbers, and other applications, and store data in the cloud.

HOBOmobile also makes it fast and easy to set up audible alarm notifications so users are immediately notified of problems. For example, if CO₂ concentrations in a school go beyond a set threshold, or humidity conditions reach a point where mould could develop, the MX1102 logger will beep and display alarm notifications so users can take corrective action.

“The MX1102 sets a new standard for CO₂ monitoring by dramatically reducing the time and costs associated with having to connect data loggers to a computer to download the data,” said Herman Gustafson, Product Marketing Manager, Onset. “This is a particular advantage in facilities where multiple loggers are being used. And, it makes CO₂ monitoring more feasible in applications such as monitoring ventilation systems, where physically downloading data from the logger may be difficult.”

Jim Copeland, Managing Director at Onset’s primary UK distributor, Tempcon , commented: "This latest addition to the MX range represents a genuinely portable and wireless solution for measuring CO₂, temperature and humidity. Onset is leading the way in combining the benefits of Bluetooth access with battery powered portability and research grade measurements. The MX1102 ticks so many boxes, it's a game changer."
