DESCRIPTION

· The ZMOD4410 Gas Sensor Module detects TVOC, estimates CO2, and monitors IAQ.

· It operates reliably in humid, dusty, and wet conditions.

· The module includes a gas sensing element and a CMOS signal conditioning IC.

· It uses a Si-based microhotplate with a metal oxide chemiresistor for sensing.

· The ASIC controls sensor temperatures and measures MOx conductivity.

· Data is read via I2C interface and processed by a microprocessor.

· Firmware supports AI and machine learning for various outputs.

· Suitable for low-voltage and ultra-low power battery applications.

FEATURES

· AI-based sensor output for TVOC, IAQ, and eCO2 measurements.

· Absolute TVOC output for PBAQ standards.

· Relative IAQ output based on TVOC and odor changes.

· Algorithm to discriminate sulfur-based odors.

· Compensation for humidity, temperature, and oxidizing gases.

· High sensitivity to Hydrogen (H2).

· Ultra-low power consumption down to 200µW.

· Siloxane resistant and JEDEC JESD47 qualified for 10 years.

· Supply voltage: 1.7V to 3.6V, RoHS compliant.

· Water and dustproof version available (IP67 certified).

· Package: 12-LGA, sizes: 3.0 × 3.0 × 0.7 mm (standard), 3.0 × 3.0 × 0.9 mm (IP67).

APPLICATIONS

· Indoor air monitoring for UBA and PBAQ standards.
