Wireless Carbon Dioxide CO2 Sensors

Elevated carbon dioxide (CO₂) levels in indoor environments can impact health, comfort, and productivity.  Causing symptoms like fatigue, headaches, and nausea.

To prevent these risks, it’s essential to monitor CO₂ concentration all the time and respond quickly when levels rise. Monnit’s Wireless CO₂ Sensors offer a reliable solution.

These smart sensors track real-time CO₂ levels.  They instantly alert designated personnel via text or email when concentrations exceed safe thresholds.  Ensuring a safer and more efficient environment.

Wireless Carbon Dioxide CO2 Sensors provide accurate, real-time CO₂ monitoring for safer, smarter environments

Monnit’s Wireless Carbon Dioxide (CO₂) Sensors offer reliable insight into indoor air quality and ventilation performance. Monitoring CO₂ levels in HVAC systems, greenhouses, or enclosed marine vessels is crucial for ensuring safety, comfort, and productivity.  These sensors help optimise HVAC calibration, improve ventilation efficiency, and support CO₂-sensitive environments like grow rooms.


How It Works

When CO₂ levels exceed preset thresholds, the system immediately alerts designated personnel via text, email, or phone call. This allows for rapid response and ensures air quality remains within safe limits.


Fast, Hassle-Free Installation

Installation takes as little as 15 minutes.  The sensor comes in a single, easy-to-deploy model powered by AA batteries with up to 10 years of battery life. For added flexibility, line-power options with battery backup are also available.


Easy Management with iMonnit Software

Managing your sensors is simple with iMonnit Cloud Sensor Management Software. The platform supports a range of subscription plans.  From Basic to Premier—allowing monitoring and management of up to 99 sensors. The software provides real-time CO₂ readings, historical data trends, and intuitive dashboards for complete visibility.
