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.

[a]

The abbreviation ppm stands for “parts per million,” and ppb is an abbreviation for “parts per billion” (e.g., 1ppm equals 1000ppb).

[b]

Conversion from ppm to mg/m3 for most common TVOC is by the factor approximately 2 (e.g., 5ppm equals approximately 10mg/m3).

Response times depend on TVOC gas and concentration.
