The Siemens QPA1064 is a room air quality sensor that measures both CO2 concentrations and temperature, designed to optimize ventilation and energy consumption in indoor environments. It features a maintenance-free CO2 sensing element based on non-dispersive infrared (NDIR) technology, ensuring long-term stability and eliminating the need for recalibration. With signal outputs of DC 0–10 V or 4–20 mA, this sensor is ideal for integration into building automation systems to improve room comfort and energy efficiency.

Key Features:

• CO2 sensing range: 0–2000 ppm
• Temperature range: 0–50°C
• Maintenance-free CO2 sensor (NDIR technology)
• Signal outputs: DC 0–10 V or 4–20 mA
• Recalibration-free for 5 years
• IP30 protection rating
