Case for PMS5003 air quality sensor and Raspberry Pi Zero W

thingiverse

This is a case for mounting a PMS5003 particulate sensor and a Raspberry Pi Zero W. It is part of DIY air quality monitoring system I built that collects PM1.0, PM2.5 and PM10.0 particulate data every second and stores it in a database. The case has builtin standoffs for the Pi Zero compatible with M2.5 screws. It also has 4 M2.5-compatible screw holes for attaching the cover. The case has cutouts for a power cord, the sensor's intake fan, and the 4 holes in the sensor for air outflow. The software is freely [available on github](https://github.com/jelson/aqi). It consists of two components: a client and server. The client runs on the Pi, reads data via serial port from the sensor and sends it via HTTPS to the server. The server is a small web service that accepts data from the client and writes it to a Postgres database. The data in the database can be easily visualized using tools such as Grafana, a screenshot of which is shown.
