3 Essential Measurements in One Device

CO₂ Monitoring

CO₂ levels can increase when indoor spaces are poorly ventilated or occupied by many people.

The QP CO₂ monitor measures concentrations from 400 to 9,999 ppm, allowing you to monitor changes and identify when additional ventilation may be needed.

Temperature

Monitor indoor temperature from -20°C to 50°C to better understand your room’s environmental conditions.

Relative Humidity

Track relative humidity from 0–99.9% RH to help maintain a more comfortable indoor environment.

Accurate CO₂ Monitoring

The monitor uses an NDIR CO₂ sensor designed for reliable long-term measurement. The sensor is factory calibrated and supports automatic calibration to help maintain accurate readings over time.

For automatic calibration to work effectively, the device should periodically be exposed to outdoor-level CO₂ concentrations of approximately 400–500 ppm.

Monitor Your Environment Over Time

The QP CO₂ monitor can connect to the Qingping IoT app, allowing you to configure monitoring settings, recording intervals, upload frequency, and alert thresholds.

The device can save up to 2,880 sets of data locally, equivalent to approximately 30 days when readings are recorded every 15 minutes.

This makes it easier to identify changes in indoor conditions and understand how factors such as occupancy and ventilation affect CO₂ levels.

Long Battery Life

The built-in 2,600 mAh lithium battery provides approximately 35 days of operation when uploading data every 10 minutes, although actual battery life depends on your recording and upload settings.

USB-C charging provides a convenient way to recharge the device when needed.

Designed for Homes & Workplaces

The compact QP CO₂ monitor is suitable for:

• Homes and apartments
• Bedrooms
• Home offices
• Corporate offices
• Classrooms
• Meeting rooms
• Training facilities
• Healthcare and commercial spaces

Its small footprint allows it to sit comfortably on a desk, shelf, or other convenient location.

Technical Specifications

*Battery life varies depending on recording and data-upload settings. Avoid prolonged use in environments with humidity above 90%.
