Data logger: Onset Computer Corp.
Onset introduced the HOBO MX1102, a data logger that records and transmits carbon dioxide, temperature, and rh data wirelessly to mobile devices via Bluetooth Smart. Building off Onset’s HOBO MX1101 Bluetooth temperature and humidity logger, the self-contained MX1102 is ideal for indoor air quality studies and environmental monitoring in schools, hospitals, laboratories, and other environments. It measures CO2 over a range of 0 – 5,000 parts per million (ppm) and enables users to access the data from mobile devices within a 100-ft 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 it 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.
