Dual Infrared Stability: Featuring dual-channel NDIR infrared technology, this CO2 monitor ensures CO₂ concentration stays stable. Automatic supply and ventilation respond precisely, while real-time readings and trend curves offer clear monitoring, making level control more reliable and effortless

Plant & Human Modes: Switch seamlessly between plant and human modes with our carbon dioxide sensor. Automatic CO₂ supply or ventilation responds to environmental levels, while manual adjustments enable precise control of indoor air or greenhouse CO₂ generators, keeping spaces balanced efficiently

Smart Light Detection: Automatic light-sensing with this CO2 regulator ensures CO₂ is delivered only during the day and paused at night. In human mode, ventilation decisions stay consistent regardless of light, preventing gaps or accidental stoppages and maintaining controlled indoor air

High-Level Alert System: This indoor air quality monitor combines audible alerts and high-limit ventilation to manage CO₂ spikes. When concentrations exceed set thresholds, rapid airflow starts automatically, with screen warnings matching fan operation for immediate, real-time control of indoor air levels

Easy Setup Operation: Start monitoring instantly with VEVOR carbon dioxide controller. A brief 10-second countdown brings the device online. Large LCD shows CO₂ levels, temperature, humidity, and operational status. Key logic enables easy adjustment of alarm values and auto-calibration, ideal for beginners
