7. Sensor Module Characteristics 7.1 Gas Sensor Module Characteristics
The ZMOD4510 Gas Sensor Module detects typical outdoor 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 a combined Air Quality Index based on the EPA standard. The sample rate to execute the sequence and detect outdoor air is 60 seconds. The sensor does not require an active or direct airflow onto the sensor module since diffusion of ambient gas does not limit the sensor response time.
Important:
The ZMOD4510 can also detect safety-relevant gases; however, the sensor 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 IDT disclaims all liability for any such use.
