Make air quality tangible, local, and measurable for students. The Go Direct Air Quality Sensor transforms air quality from an abstract concept into measurable evidence in a classroom-ready form. It equips educators and students with the tools needed to investigate pollution scientifically, think systemically, and understand how environmental conditions directly affect human and ecological health—right where they live and learn.

Includes 3 AP- and NGSS-Aligned Lessons

  • Using the Sensor: Learn different channels, remote data collection, and basic analysis.
  • Indoor Air Quality Investigation: Analyze indoor air quality data and develop recommendations to improve it.
  • Traffic and Outdoor Air Quality: Investigate how vehicle traffic affects air pollution.

Extended Investigation Ideas

  • Compare indoor and outdoor air quality.
  • Monitor particulate matter near roads, parking lots, or green spaces.
  • Analyze air quality changes during traffic peaks or daily weather shifts.
  • Observe ozone trends on sunny vs. cloudy days.
  • Investigate how different types of cooktops affect CO2 and PM levels.

Measures Key Air Pollutants

  • Particulate Matter (PM1, PM2.5, and PM10)
  • Ground-Level Ozone (O3)
  • Nitrogen Dioxide (NO2)
  • Sulfur Dioxide (SO2)
  • Carbon Dioxide (CO2)
  • Volatile Organic Compound Index (VOC Index)

Measures Environmental Conditions

  • Temperature 
  • Relative Humidity 
  • Barometric and Station Pressure

Key Features

  • Real-time air quality data collection via Bluetooth® wireless technology
  • Remote data logging for long-term or remote investigations, no connection required
  • Integrated Global Navigation Satellite System (GNSS) allows for geotagging
  • Durable for indoor and outdoor use

Remote Data Logging—Go Beyond Wireless Limits!

This Go Direct sensor is capable of remote data logging! This feature allows sensors to store data directly to their internal memory—ideal for investigations that extend beyond typical connection ranges like long-term environmental monitoring or rocket launches. It works seamlessly with our award-winning Vernier Graphical Analysis® app so students can visualize their data and make key connections between abstract science concepts and real-world phenomena.

Rechargeable Battery—Ready When You Are

The robust rechargeable battery offers long battery life and provides always-ready operation when using the sensor wirelessly. Monitor battery life directly from our award-winning Vernier Graphical Analysis® app, as well as LabQuest® 3. Should the battery run low, simply connect the sensor to the charging cable and keep on collecting—no interruptions or inconvenience to you or your students.

Wireless or Wired—The Flexibility to Choose

Our Go Direct sensors connect directly to your mobile device, Chromebook, or computer using our Vernier Graphical Analysis® app—no additional equipment or software purchases are necessary. Go Direct sensors can be used wired via USB or wirelessly via Bluetooth® wireless technology, allowing you to choose the best solution for your classroom or laboratory.
