Gas Sensor Module for Refrigeration Air Quality ZMOD4450 Datasheet Description 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; for example, food storage and shipping.
The sensor is a 12-pin 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 a heater element on a silicon-based MEMS structure and a metal temperature sensor.
It 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’...
