Current conditions
Display temperature, humidity, air-quality, and grain-moisture readings from the current device row.
Community / App case study
SiloGuard
A connected rice-storage monitoring prototype combining ESP32 telemetry with realtime temperature, humidity, air-quality, and moisture dashboards, mold-risk scoring, alerts, rollups, and actuator commands.
Connected rice-storage monitoring prototype
- React
- TypeScript
- Supabase
- ESP32
- Realtime
01 / Overview
What it’s built for.
Connect device readings to current-condition cards, historical trends, risk labels, alerts, and actuator command state.
Who it serves
Researchers and operators exploring environmental readings in rice storage.
02 / Features
Inside the app.
History and alerts
Inspect bounded historical ranges, mold-risk scores, cooldown-protected alerts, and rollups.
Command state and reports
Review manual/auto actuator command state and print the selected range’s data report.
03 / Workflow
From task to outcome.
The configured ESP32 collects and publishes readings.
Supabase updates the current row and records throttled history.
The dashboard receives realtime changes and loads selected history.
Review risk labels, alerts, command state, and a printable report.
04 / Technical layers
How the pieces work.
React · TypeScript · Tailwind
The Vite dashboard presents current cards and on-demand history.
ESP32 · Supabase · Vercel functions
The documented device path writes directly to Supabase; the repository also includes ingestion and actuator API functions.
PostgreSQL · Realtime · Triggers
Current readings, history, alerts, rollups, and command records connect through device-scoped policies.
Weighted sensor thresholds
The prototype computes a mold-risk index from humidity, temperature, gas, and moisture scores.
05 / Limitations
What to keep in mind.
- Missing Supabase configuration produces demo readings.
- Risk scores are prototype threshold calculations, not independently validated mold detection.
- Software dashboards do not establish sensor calibration, actuator behavior, or physical pilot acceptance.
