ZMOD4510 Gas Sensor Module for Outdoor Air Quality

IDT's digital outdoor air quality sensor for ozone and nitrogen oxide gas detection is ideal for high-volume applications

Image of IDT's ZMOD4510 Gas Sensor Module IDT's ZMOD4510 is a software-upgradeable, digital outdoor air-quality sensor that is designed for high-volume applications. This sensor has the capability to detect ozone (O3) and nitrogen oxide (NOx) gases which are two significant causes of unhealthy outdoor air quality. The ZMOD4510 can quantify combined O3 and NOx in concentrations as low as 20 parts per billion (ppb). The outdoor air sensor offers flexibility, small size, and low power consumption, which is an ideal combination for a wide variety of industrial and consumer applications.

For users that are working on HVAC systems, industrial cameras, home automation systems, smart air purifiers, smartwatches, and other wearable devices, the ZMOD4510 is an ideal sensor solution that can target multiple aspects of outdoor air quality with improved energy efficiency, high sensitivity, and reliability. The sensor can be integrated into designs quickly thanks to precompiled firmware and the pre-calibration of the ZMOD4510 sensors, which lowers customer production costs.

The ZMOD4510 provides reliable detection that correlates with the US Environmental Protection Agency’s (EPA) air quality index for measuring O3 and NOx. It is based on proven metal oxide (MOx) material and each sensor is calibrated electrically with gas to ensure consistency from lot to lot which is an important advantage for manufacturers with long production runs. The ZMOD4510 devices are highly resistant to siloxanes making it ultra-reliable in harsh applications.
