Onset’s HOBO MX1102 CO2 logger makes it more convenient than ever to measure and record CO2 in buildings and other noncondensing environments. It measures CO2 from 0 – 5,000 parts per million (ppm) – and our free HOBOconnect app allows you to access data right from your mobile phone or tablet within a 100-foot range.
The MX1102 also features a USB port so it can be used with a computer running HOBOware Pro graphing and analysis software.
Remotely access your data in Onset’s cloudbased HOBOlink software with the new MX Gateway.

Pressure Dependence | 0.13% of reading per mm Hg (corrected via user input for elevation/altitude) |
Operating Pressure Range | 950 to 1,050 mbar (use Altitude Compensation for outside of this range) |
Compensated Pressure Range | -305 to 5,486 m (-1,000 to 18,000 ft) |
Sensing Method | Non-dispersive infrared (NDIR) absorption |
Response Time | |
Temperature | 12 minutes to 90% in airflow of 1 m/s (2.2 mph) |
RH | 1 minute to 90% in airflow of 1 m/s (2.2 mph) |
CO2 | 1 minute to 90% in airflow of 1 m/s (2.2 mph) |
Logger | |
Radio Power | 1 mW (0 dBm) |
Transmission Range | Approximately 30.5 m (100 ft) line-of-sight |
Wireless Data Standard | Bluetooth Smart (Bluetooth Low Energy, Bluetooth 4.0) |

Building Reliable Systems: Hydroelectric Dam Monitoring in Western Pennsylvania
Hydroelectric dams are a source of renewable energy, and many have taken the place of fossil fuel reliance across the United States. While they provide green energy to the grid, they also impact the environment above and below the dam. 
 
In order to protect these habitats and mitigate any potential harm, hydroelectric dam operators monitor water quality conditions above and below the dam to ensure conditions meet ecosystem needs. Eagle Creek Renewable Energy has several hydroelectric plants positioned throughout Pennsylvania, and each is managed and monitored by a team of professionals. 
 
One of these managers is Craig Goldinger, a regional manager with Eagle Creek Renewable Energy in Western Pennsylvania.

Environmental monitoring in the Caribbean may be essential, but it has also historically been placed on the back burner. Albert Jones, Instrumentation Officer for the Caribbean Community Climate Change Centre (CCCCC), explains, “Data collection itself is not what is considered one of those sexy activities where you can easily get funding.” 
 
Still, monitoring the water surrounding island nations is necessary to protect residents and the environment. The CCCCC works to establish environmental monitoring networks and systems in the Caribbean. One aspect of Jones’ work centers around data buoy instrumentation and deployment,—equipment that will be used to support Ecoforecasts for Coral Health Monitoring and to provide valuable environmental data to the public.
Read MoreProtecting Chicago's Lakefront: Freshwater Beach Monitoring
Thousands of people flock to the Great Lakes every year to enjoy the freshwater beaches along the coast. As an urban hub with over 2.5 million residents, beachfronts in Chicago have regular visitors as well as tourists that recreate in the bordering Lake Michigan. 
 
According to the Chicago Park District, it is estimated that more than 100,000 residents and visitors per day use Chicago’s Lakefront trail during summer weekends. 
 
Proximity to the Lake is not only a recreational activity for Chicagoans, but also a part of the city’s history due to its role in domestic and international shipping routes. In addition, the Lake serves as a drinking water source and as an essential climate regulator in the region that acts as a natural air conditioning affect.
