Overview
The Onset HOBO MX1102 CO2 logger makes it more convenient than ever to measure and record CO2 in buildings and other non-condensing environments. It measures CO2 from 0–5,000 parts per million (ppm). The free HOBOconnect app allows users to access data right from a mobile phone or tablet within a 100-foot range. Remotely access data in Onset’s cloud-based HOBOlink software with the new MX Gateway.

Mechanics
The MX1102 also features a USB port, so it can be used with a computer running HOBOware Pro graphing and analysis software.

RH Sensor
Range

1% to 90% RH (non-condensing)

Accuracy ±2% from 20% to 80% typical to a maximum of ±4.5% including hysteresis at 25°C (77°F); below 20% and above 80% ±6% typical
Resolution 0.01%
Drift <1% per year typical
CO2 Sensor
Range 0 to 5,000 ppm
Accuracy

±50 ppm ±5% of reading at 25°C (77°F), less than 90% RH non-condensing and 1,013 mbar

Warm-up Time 15 seconds
Calibration Auto or manual to 400 ppm
Non-linearity <1% of FS
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)
Logger Operating Range 0° to 50°C (32° to 122°F); 0 to 95% RH (non-condensing)
Logging Rate 1 second to 18 hours
Logging Modes Fixed interval (normal, statistics) or burst
Memory Modes Wrap when full or stop when full
Start Modes Immediate, push button, date & time, or next interval
Stop Modes When memory full, push button, date & time, or after a set logging period
Time Accuracy ± 1 minute per month at 25°C (77°F)
Power Source 4 AA 1.5 Volt batteries (user replaceable) or USB power source (5 V DC, 2 Watts) 
Battery Life 6 months, typical with logging and sampling intervals of 5 minutes or slower; 6 months or less with logging and sampling intervals faster than 5 minutes while logging CO2. Entering burst logging mode will impact battery life. With app use, battery life can be reduced by remaining connected, excessive readouts, audible alarms, and paging. Visual/audible alarms and other events can have a marginal impact on battery life.
Memory 128 KB (84,650 measurements, maximum)
Download Type USB 2.0 interface or via Bluetooth Smart
Full Memory Download Time 20 seconds via USB; approximately 60 seconds via Bluetooth Smart, may take longer the further the device is from the logger
LCD LCD is visible from 0° to 50°C (32° to 122°F); the LCD may react slowly or go blank in temperatures outside this range
Size 7.62 x 12.95 x 4.78 cm (3.0 x 5.1 x 1.88 inches)
Weight 267.4 g (9.43 oz)
Environmental Rating IP50

Wildfire Prevention in the Sierra Nevada Region with the Yuba Watershed Institute

Though recent wildfires have sparked new conversations about wildfire management and response, groups like the Yuba Watershed Institute have been monitoring the forests and water resources of the Sierra Nevada region for decades, managing approximately 5,000 acres of land with the Bureau of Land Management (BLM) and about 7,000 acres in private land partnerships. The goal of the Institute is to work with local communities and land agencies to improve watershed and forestry management through informed practices and public outreach. The goals of the Yuba Watershed Institute are three-fold: Improve the ability of fire suppression agencies like the California Department of Forestry and Fire Protection ( CAL FIRE ) and the US Forest Service.

Wave Sensors Integration with NexSens Buoys: A Cutting-Edge Solution for Wave Measurment

Real-time wave data supports accurate weather prediction, safe and efficient maritime operations, and provides valuable safety and operating condition information for recreation and commercial fishing. Understanding wave dynamics also helps with the design of protective coastal structures like seawalls, breakwaters, and jetties. It also supports better prediction of their impact on sediment transport and coastal geomorphology. Wave data is a key factor in qualifying and designing offshore wind farms and harnessing kinetic energy for electrical generation. It helps with the understanding of ocean-atmosphere interactions and contributes to studies of sea-level rise and climate change impacts.
