IoT End to End
summary
Sensor reads from an Arduino attach to an Intel NUC edge gateway, run Node‑RED flows that throttle to one message every five seconds and publish over MQTT to Bluemix. Data lands in the Watson IoT platform, triggers rules and Twilio SMS alerts when temperature >80°F, and gets stored in Cloudant (~3,700 records). A Jupyter notebook uses Apache Spark and PixieDust visualization to compute mean 80.69°F, std dev ~3, min 73, max 105 and surface anomalies.
