IOT Air Sensor MonitorBuild a 3D printed enclosure for your IOT Air Quality Sensor. This project is similar to our other air quality sensor guide, except it uses Adafruit STEMMA sensors and has minimal soldering required.
|
This project uses sensors to measure PM2.5 (particles that are 2.5 microns or smaller in diameter) dust concentrations, temperature and humidity.
This weatherproof enclosure is modeled after a silo-home. We've included different types of mounting holes and brackets for different mounting configurations.
Adafruit IOBuild an Adafruit IO Dashboard to visualize your air quality sensor's data at a glance. Adafruit IO is free and includes up to 30 days of storage for your sensor's data. You can view and interact with this data from anywhere in the world with a wireless connection. |

Enclosure DesignThe case is themed to resemble a modern silo grain bin house. The roof is removable by unscrewing the top from the case. The Feather boards are securely mounted inside via heat set inserts. A mounting plate is used to secure the enclosure to a surface. Weatherproof cable gland is used to keep moisture out. The bottom cover is modular allowing for a different set of sensors. |

Choose Your SensorsThe enclosure and code accommodate for two different sets of sensors. Take a moment to choose your set up.
