Product details

I²C digital air-quality sensor for indoor IAQ monitoring

The ZMOD4510AI4R is a Renesas OAQ (Outdoor Air Quality) integrated sensor that reports air-quality data over an I²C digital interface — no external ADC or analog conditioning needed on the host PCB. Rated accuracy of ±2% gives the system designer a known measurement tolerance for IAQ algorithms, whether the target is CO₂-equivalent or total VOC estimation. Supply voltage is 1.7 V, which lets the sensor run directly from a 1.8 V rail without a separate LDO, simplifying the power tree in battery-powered or low-voltage designs.

Operating temperature and environment constraints

The -40°C to 65°C range covers indoor HVAC, smart-building, and cold-chain monitoring, but the 65°C ceiling excludes applications like engine-bay air quality or direct-sunlight rooftop enclosures without active cooling. At 11 µA switching current (typical), the sensor's power budget is low enough for always-on sensing in battery-operated thermostats or portable air monitors.

Frequently asked questions

What is the I²C output interface of the ZMOD4510AI4R?

The sensor communicates over a standard I²C bus. This means it connects directly to the SDA/SCL pins of any MCU with an I²C peripheral — no level shifting needed if the MCU runs at 1.8 V, and the 1.7 V supply rail matches typical 1.8 V logic domains.

Can the ZMOD4510AI4R be used outdoors?

The operating temperature range is -40°C to 65°C. That covers most sheltered outdoor installations (e.g., under an eave, inside a weatherproof enclosure) but direct sun exposure or proximity to a heat source can push the ambient above 65°C. For continuous outdoor use in hot climates, check the thermal profile of the enclosure.
