ZMOD4410AI1R

ZMOD4410AI1R is a gas sensor module for TVOC and indoor air quality. It is designed for easy implementation to detect total volatile organic compounds (TVOC), estimate CO2, and monitor indoor air quality (IAQ). The module works reliably in various conditions, including very humid and dusty applications with the possibility of water spray, condensation, or immersion. The small LGA assembly consists of a gas sense element and a CMOS signal conditioning IC. The sensing element is a Si-based micro hotplate with a robust and highly sensitive metal oxide (MOx) chemoreceptor. Typical application includes indoor air monitoring to meet UBA and typical public building air quality (PBAQ) standards, monitoring home, office, personal, and bathroom environments for healthy conditions and comfort, detecting hazardous materials and unhealthy conditions (e.g., fumes from construction materials), automation based on indoor ambient air quality (HVAC, air purifiers, thermostats, kitchen hoods, etc.).

• Absolute measurement of total organic compound concentrations and indoor air quality to meet UBA std
• Estimated carbon dioxide level (eCO2)
• Absolute TVOC output to meet public building air quality (PBAQ) standards
• Relative IAQ based on TVOC and odour changes
• Algorithm to discriminate sulphur-based odours
• High sensitivity to hydrogen (H2) based on resistance output
• Built-in non-volatile memory (NVM) for module specific data (configuration and calibration)
• Excellent for low-voltage and ultra-low power battery applications
• No external trimming components required, external reset pin (active-LOW)
• 12-LGA package, temperature range from -40°C to +65°C
