Davis Instruments AirLink Air Quality Sensor

It delivers precise, hyper-local PM2.5 and PM10 readings that integrate beautifully with WeatherLink stations, making it invaluable during wildfire season or for monitoring chronic air pollution.

The Davis Instruments AirLink Air Quality Sensor is a purpose-built monitoring device designed to complement a home weather station setup by tracking particulate matter levels in the air around your property. Using a laser particle counter, it measures PM1.0, PM2.5, and PM10 concentrations with the kind of precision that serious weather enthusiasts and health-conscious households expect from Davis hardware. The unit is compact and weatherproof, intended for either outdoor mounting to capture ambient air conditions or indoor placement to monitor air quality within living spaces, giving users a comprehensive picture of both outside pollution sources and indoor air cleanliness.

What sets the AirLink apart in the Weather Stations accessory category is its seamless integration with Davis's WeatherLink ecosystem, including compatibility with Vantage Vue, Vantage Pro2, and other WeatherLink-enabled consoles. Data from the sensor feeds directly into the WeatherLink app and website, where it's translated into an easy-to-read Air Quality Index alongside your existing temperature, humidity, wind, and rainfall data. This consolidation means users don't need a separate app or dashboard to track pollution levels; instead, air quality becomes just another data layer within the same trusted interface they already rely on for daily weather monitoring, complete with historical trends and real-time alerts when conditions become hazardous.

Built for durability and continuous operation, the AirLink features a fan-based intake system that actively draws air across its sensor to ensure accurate, consistent readings even during temperature swings or high humidity. It's particularly valuable for regions prone to wildfire smoke, agricultural dust, or urban smog, giving homeowners actionable insight into when to close windows, limit outdoor activity, or run air purifiers. For Davis Instruments users already invested in professional-grade weather tracking, the AirLink sensor extends that same level of reliability and data richness into the realm of air quality, making it a natural and worthwhile addition to any comprehensive home weather monitoring system.
