The Upgraded ALTA^® Wireless Carbon Dioxide (CO₂) Sensor Now Delivers Ambient Temperature and Pressure Monitoring

Carbon dioxide (CO₂) may be invisible, but it can significantly affect people, processes, and productivity. From commercial buildings and classrooms to breweries, greenhouses, laboratories, and industrial facilities, monitoring CO₂ levels is essential to maintain healthy environments, optimize operations, and protect occupants.

Monnit has enhanced its ALTA^® Wireless Carbon Dioxide (CO₂) Sensor with new sensing capabilities that provide even greater accuracy and visibility into environmental conditions.

In addition to instantaneous CO₂ readings and 8-hour Time Weighted Average (TWA) CO₂ data, the upgraded sensor now delivers ambient temperature and pressure measurements from a single wireless device.

Whether you're managing indoor air quality (IAQ), optimizing ventilation, supporting plant growth, or protecting workers in confined spaces, the enhanced ALTA CO₂ Sensor provides actionable data to support informed decisions.

Why Monitor Carbon Dioxide?

CO₂ levels are one of the most effective indicators of IAQ and ventilation performance. Elevated concentrations can cause fatigue, headaches, reduced concentration, and lower productivity. In some industrial and agricultural environments, excessive CO₂ accumulation can also create serious safety risks.

Organizations rely on CO₂ monitoring to:

• Improve IAQ and optimize HVAC and ventilation performance
• Support Demand-Controlled Ventilation (DCV) strategies
• Protect workers in confined spaces
• Monitor fermentation processes
• Enhance greenhouse and grow-room productivity
• Track biological and scientific processes
• Improve energy efficiency while maintaining occupant comfort

What's New in the Enhanced ALTA Wireless CO₂ Sensor?

The latest version of the ALTA Wireless Carbon Dioxide Sensor introduces a high-accuracy ambient pressure-and-temperature sensing element that automatically improves CO₂ measurement accuracy.

New Ambient Pressure Monitoring

As altitude and atmospheric pressure change, CO₂ concentration measurements can be affected. The enhanced sensor automatically compensates for these environmental variations by measuring ambient pressure and adjusting CO₂ calculations accordingly.

Benefits include:

• More accurate CO₂ readings
• Automatic pressure compensation
• No manual altitude configuration required
• Improved consistency across different environments

New Ambient Temperature Monitoring

The sensor now measures ambient temperature in addition to CO₂ concentration.

Temperature data helps:

• Improve CO₂ measurement accuracy
• Provide additional environmental monitoring
• Support HVAC optimization
• Enable configurable temperature alerts and thresholds

More Actionable Data

The enhanced sensor reports:

• Instantaneous CO₂ concentration (ppm)
• 8-hour Time-Weighted Average (TWA) CO₂
• Ambient temperature
• Ambient pressure

Organizations can monitor each data point independently in iMonnit™ to set custom alert thresholds and notification rules.

Advanced CO2 Measurement Technology

The ALTA Wireless Carbon Dioxide Sensor utilizes a low-power, high-performance Non-Dispersive Infrared (NDIR) sensing element to measure CO₂ concentrations from 0 to 10,000 ppm.

Key performance specifications include:

• Measurement range: 0–10,000 ppm
• Resolution: 1 ppm
• Accuracy: ±45 ppm + 3% of reading
• Configurable auto-calibration
• Instantaneous and 8-hour TWA reporting

The sensor continuously collects measurements and reports data at user-configurable Heartbeat intervals through an ALTA Gateway to iMonnit or approved third-party systems.
