4. Sensor Module Characteristics

The ZMOD4510 Gas Sensor Module detects typical gases based on studies and international standards for outdoor air quality. Characteristic

module parameters are shown in Table 5. The ZMOD4510 uses a sequence of applied temperatures in order to sample the air and report an

Air Quality Index (AQI) based on the EPA standardi. The sensor does not require an active or direct airflow onto the sensor module because

diffusion of ambient gas does not limit the sensor response time.

Important: The ZMOD4510 can also detect safety-relevant gases; 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.
