IoT, JavaScript and Beer Brewing
summary
Claims IoT will hit 75 billion devices by 2025 and households already average about six connected devices; home inventory here measures ~28 devices (~10 per person). Practical build: an open‑source iSpindle style fermenter sensor flashed with esprino on an ESP8266 sending tilt (specific gravity) and temperature hourly. Data flows into MongoDB via Realm functions, uses aggregation pipelines, collection.watch and triggers to chart fermentation, and sends a Twilio SMS when gravity flattens. The demo occasionally hiccups but the system reliably records gravity drops and notifies when beer is ready.
