Why Your Next Hardware Project Should be Built With Nerves

Builds a desktop air quality monitor called BreatheX using BME680, Raspberry Pi 3, a NeoPixel stick and a 5V fan, total parts about $68. It samples temperature, humidity, pressure and VOCs every 10 seconds (~8,600 data points/day), writes state to a local agent, and pushes readings asynchronously to Google Cloud Datastore. Uses Nerves for concurrency, supervised processes, A/B boot partitions for safe OTA updates, and a NeoPixel color meter display; the device runs stably even without cloud connectivity.
