The ZMOD4410 gas sensor module is an easily integrated firmware configurable architecture enabling multiple sensing solutions with a common hardware platform. Simply download one of the firmware libraries that best supports your application from the Renesas website and integrate it with your host microcontroller. The JEDEC JESD47 qualified device supports 10+ years of life, supporting your indoor air quality (IAQ) application designed for detecting total volatile organic compounds (TVOCs), estimating CO2, and monitoring indoor air quality in different smell-based use cases, including very humid and dusty applications with the possibility of water spray, condensation or immersion. The miniature 12-LGA assembly consists of a gas sense element and a CMOS signal conditioning IC. The sensor is pre-calibrated with a signal conditioner controlling 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 ZMOD4410 is ideal for applications such as air purifiers, IAQ monitors, kitchen hoods, HVAC equipment, building controls, thermostats, smart fans, and other smart devices.
