The project is about creating a low-cost air quality monitoring station using the Wio Tracker L1 and Grove gas sensors (MQ5 and MQ135). It is designed for schools to measure air pollutants and visualize the data in real time through a mobile app or web dashboard.
Air pollution directly affects health and education, yet professional monitoring stations are too expensive for schools. I wanted to design an affordable, portable, and easy-to-build solution that empowers students to learn about LoRa, Meshtastic, sensors, and environmental science.
