An air quality monitor for a safer and healthier living environment. With MCO Home's MH9-CO2-WD your Z-Wave system will monitor for accurate data on CO2 concentration, volatile organic compound concentration (VOC), temperature, and humidity, and allow you to use other automated devices to maintain the air quality of your space with ease.

With its modern glass touch surface and LCD display, the MCO Home CO2 Monitor not only provides accurate air quality data but also adds a touch of sophistication to your space. The device can monitor CO2 concentration in the air, with a range of 0-5,000ppm, and activate a system alert via Z-Wave whenever your desired safety threshold is breached.

In addition, the MCO Home Air Quality Monitor also shows VOC detection in four stages: Excellent, Good, Average, and Poor, which can be checked locally. The MCO sensor can control air ventilation systems directly via integrated outputs, making it able to directly control select devices not automated via your Z-Wave system.
