Gas Sensor Module - ZMOD4450

The ZMOD4450 Gas Sensor Module is crafted for detecting gases related to food ripening or spoilage, making it perfect for refrigeration air quality applications. This compact 12-LGA assembly (3.0 × 3.0 × 0.7 mm) integrates a gas sense element and a CMOS signal conditioning IC. The sense element comprises a heater on a Si-based MEMS structure and a metal oxide (MOx) chemiresistor. The signal conditioner manages sensor temperatures and measures MOx conductivity, which correlates with gas concentration. Data can be accessed via an I2C interface for further processing by a microprocessor.

Ideal for monitoring food storage and shipping environments, the ZMOD4450 can operate in humid and dusty conditions, even with water spray, condensation, or immersion. The included firmware helps determine gas levels and predict food spoilage, making it a reliable choice for maintaining food quality.

With its low current consumption, this module is suitable for low-voltage and battery-powered applications. It also features built-in nonvolatile memory (NVM) for storing configuration and calibration data, ensuring consistent performance and easy integration into various systems.
