Digital outdoor air quality sensor for high-volume applications
Integrated Device Technology (San Jose, CA) has announced what it says is the industry's first software-upgradeable, digital outdoor air quality sensor targeting ozone and nitrogen oxides (NOx) gases for high volume applications.

The ZMOD4510 outdoor air quality sensor platform can detect ozone (O 3) and nitrogen oxides (NOx) gases - two significant causes of unhealthy outdoor air quality. The ability of the ZMOD4510 to quantify combined ozone and NOx in concentrations as low as 20 parts per billion (ppb), says the company, coupled with its combination of flexibility and small size makes it an ideal solution for a wide variety of industrial and consumer applications.

The ZMOD4510 sensor solution is capable of targeting multiple aspects of outdoor air quality with improved energy efficiency, and high sensitivity and reliability for product designers working on HVAC systems, industrial cameras, home automation systems, smart air purifiers, smartwatches, and other wearables. Complementing these advantages, says the company, the ZMOD4510 can be quickly integrated into designs thanks to precompiled firmware and the pre-calibration of all ZMOD4510 sensors, which lowers customer production costs.

"Poor outdoor air quality poses a significant health risk," says Uwe Guenther, general manager of IDT's industrial group, "which is driving demand for increasingly smart and connected devices that can detect and respond to this problem. We optimized our new ZMOD4510 gas sensor specifically for these devices, uniquely combining all the characteristics necessary for high volume production without compromising sensitivity and accuracy. These devices provide reliable detection that correlates with the US Environmental Protection Agency's (EPA) Air Quality Index for measuring O3 and NOx."

The ZMOD4510 is based on proven metal oxide (MOx) material and each sensor is calibrated electrically with gas to ensure consistency from lot to lot. The devices are also highly resistant to siloxanes for superior reliability use in harsh applications.

The ZMOD4510 is the newest member of the company's ZMOD family of gas sensors. An evaluatiuon kit - the ZMOD4510-EVK - is also avauilable.
