7. Sensor Module Characteristics 7.1 Gas Sensor Module
The ZMOD4410 Gas Sensor Module is designed to detect typical TVOC contaminations based on studies and international standards for indoor air quality. Characteristic module parameters are shown in Table 5. The response time for a gas stimulation is always within a few seconds, depending on the TVOC and its concentration. An active or direct airflow onto the sensor module is not necessary because diffusion of ambient gas does not limit the sensor module’s response time.
Important:
The ZMOD4410 also can detect safety-relevant gases for indoor air, such as carbon monoxide (CO); however, the sensor module is not designed to detect these interferants reliably and therefore it is not approved for use in any safety-critical or life-protecting applications. It must not be used in such applications, and Renesas disclaims all liability for any such use.
