Siemens QPM2100 Air Quality Sensor for CO2

This air quality sensor is designed for precise indoor air quality monitoring, specialising in carbon dioxide measurement. Made by Siemens, this equipment operates efficiently in air ducts of ventilation systems. The device ensures accurate readings with a measuring This sensor operates between -5°C and +45°C, making it suitable for various indoor environments and well-equipped for temperature and humidity monitoring.

• Maintenance-free CO2 sensing element using non-dispersive infrared measurement
• No recalibrations required, ensuring long-term reliability
• Outputs available: DC 0 to 10V, 0 to 5V or 4 to 20mA for flexible integration
• Protects against temperature and humidity with high accuracy
• Quick response time enables effective ventilation management
• Compact design with IP54 rating for versatile installation

• Ideal for use in party rooms, lounges, and conference spaces
• Monitors air quality in areas with changing occupancy levels
• Effective for energy-efficient ventilation in restaurants and canteens
• Utilised in shopping centres and exhibition halls for optimal comfort
• Supports building automation when used with control systems

It uses real-time data on CO2 concentrations to adjust ventilation rates, thereby optimising air quality dynamically based on the number of occupants. This enhances comfort and reduces energy consumption.

The sensor offers adjustable output signals including DC 0–10V, DC 0–5V, and 4–20mA. This versatility allows seamless integration with various building management systems.

Operating outside the specified limits of -5°C to +45°C may lead to inaccurate readings and potential damage to the device, as it is not designed for harsh environmental conditions.

The sensor is designed to be maintenance-free, eliminating the need for recalibrations, ensuring consistent performance across its service life of up to eight years.
