Detection for formaldehyde with defined interference considerations - Gas detected: formaldehyde - Interference gases: alcohol, carbon monoxide and other gases Output interfaces for easy integration - DAC: 0.4 to 2.0 V standard voltage signal - UART: 3.0 V level output Power, protection and compatibility - Operating voltage: 3.7 to 9 V - Includes reverse voltage protection for safe integration Measurement range and precision - Range: 0 to 5 ppm - Resolution: ≤ 0.01 ppm Performance and response - Warm-up time: ≤ 3 minutes - Response time: ≤ 60 seconds - Recovery time: ≤ 60 seconds Use scenarios - Indoor air quality monitoring in homes, offices, or laboratories to track formaldehyde from building materials, paint, or furniture - Industrial safety and process monitoring in facilities where formaldehyde is used or produced - Portable or embedded monitoring in HVAC systems, data loggers, or field surveys for regulatory compliance and safety checks
