ZMOD4410

Gas Sensor Module for TVOC and Indoor Air Quality ZMOD4410 Datasheet Description The ZMOD4410 Gas Sensor Module is designed for detecting total volatile organic compounds (TVOC) and monitoring indoor air quality (IAQ) in different use cases. It 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 heater element on a Si-based MEMS structure and a metal oxide (MOx) chemiresistor. The signal conditioner controls the sensor temperature 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 to determine the TVOC concentration, IAQ rating, and estimated carbon dioxide (eCO2) level. Alternatively, depending on the operation mode, the ZMOD4410 software can generate a control signal, which can trigger actions based on odor levels. With its low o...
