Gas Sensor Module RENESAS ZMOD4410AI1V Featuring MOx Chemiresistor for Indoor Air Sensing
Product Overview
The ZMOD4410 Gas Sensor Module is a 12-pin LGA assembly designed for detecting total volatile organic compounds (TVOC) and monitoring indoor air quality (IAQ). It integrates a gas sense element with a CMOS signal conditioning IC to measure MOx conductivity, which correlates to gas concentration. The module offers an I2C interface for data retrieval, enabling microprocessors to determine TVOC concentration, IAQ rating, and estimated carbon dioxide (eCO2) levels. It also features an algorithm to generate a control signal for triggering actions based on odor levels. With low operating current consumption, it is ideal for battery-powered applications. Built-in nonvolatile memory stores configuration and user data.
