The Go Direct™ Air Quality Sensor helps students transform air quality from an abstract concept into measurable scientific data. Designed for environmental science, agricultural science, chemistry, and Earth science courses, this versatile sensor enables learners to investigate the quality of the air around them through real-time monitoring of key pollutants and environmental conditions. Students can collect evidence-based data to better understand how air quality affects human health, ecosystems, and local communities. The sensor measures multiple air quality indicators, including particulate matter, carbon dioxide, ozone, nitrogen dioxide, sulfur dioxide, and volatile organic compounds, while also recording temperature, humidity, and pressure. This broad range of measurements allows students to examine complex environmental interactions and develop a deeper understanding of pollution sources, atmospheric processes, and environmental change.

Investigations can include comparing indoor and outdoor air quality, studying the effects of vehicle traffic, monitoring pollution near green spaces, or analyzing how weather conditions influence air quality. Wireless Bluetooth connectivity and USB support provide flexible data collection options across a variety of devices, while remote data logging enables long-term monitoring without requiring a constant connection. Integrated GNSS technology adds location data to measurements, allowing students to map pollution patterns and conduct place-based environmental investigations. These capabilities help students build skills in data collection, analysis, interpretation, and scientific communication while exploring authentic environmental issues.

Designed for classroom, laboratory, and field use, the Go Direct™ Air Quality Sensor supports inquiry-based learning through hands-on investigations that connect scientific concepts to real-world challenges. By collecting and analyzing environmental data from their own communities, students gain practical experience with modern monitoring technology while developing a stronger understanding of environmental stewardship, public health, and sustainability.
