The ZMOD4510 is a software-upgradeable digital outdoor air quality sensor designed for high volume applications. The sensor has the ability to detect ozone (O3) and nitrogen oxides (NOx) gases, two important causes of unhealthy outdoor air quality. The ZMOD4510 can quantify the total amount of O3 and NOx down to 20 parts per billion (ppb). Outdoor air sensors offer flexibility, small size, and low power consumption, making them an ideal combination for a variety of industrial and consumer applications.

For users working on HVAC systems, industrial cameras, home automation systems, smart air purifiers, smart watches and other wearable devices, the ZMOD4510 is an ideal sensor solution that can target multiple aspects of outdoor air quality, improve energy efficiency, High sensitivity and reliability. With precompiled firmware and pre-calibration of the ZMOD4510 sensor, the sensor can be quickly integrated into the design, reducing production costs for customers.

The ZMOD4510 provides reliable detection in relation to the Air Quality Index used by the US Environmental Protection Agency (EPA) to measure O3 and NOx. It is based on proven metal oxide (MOx) materials, and each sensor is electrically calibrated with gas to ensure batch-to-batch consistency, an important advantage for manufacturers with long runs. The ZMOD4510 device is highly resistant to siloxanes, making it extremely reliable in harsh applications.
