Breathe easy, knowing that you can track and sense the quality of the air around you with this PM2.5 Air Quality Sensor with I2C Interface particulate sensor. Mad Max & Furiosa definitely should have hooked up one of these in their truck while scavenging the dusty desert wilderness of post-apocalyptic Australia. And for those of us not living in an Outback dystopia, this sensor is great for monitoring air quality, in a compact plug-in format.
