Gas Sensor Module - ZMOD4450
All prices are VAT included
The ZMOD4450 Gas Sensor Module is designed for detecting gases associated with food ripening or rotting, and is targeted for use in refrigeration air quality (RAQ) applications (eg, food storage and shipping, including humid and dusty applications with
the possibility of water spray, condensation, or immersion). It is a 12-LGA assembly (3.0 × 3.0 × 0.7 mm) that consists of a gas sense element and a CMOS signal conditioning IC. The module's sense element consists of heater element on a Si-based MEMS structure and a metal oxide (MOx) chemiresistor. The signal conditioner controls the sensor temperatures and measures the MOx conductivity, which is a function of the gas concentration. The measurement results can be read via an I2C interface with the user's microprocessor, which processes the data.
The provided firmware can be used to determine the level of gases present and to indicate the likelihood of food spoilage. With its low operating current consumption, the ZMOD4450 is an excellent choice for low-voltage and low-power battery applications. Built-in
nonvolatile memory (NVM) stores the module configuration and calibration data.
