Automated Monitoring and Alerting for Sensor Readings

• Monitor sensor data in real-time for critical thresholds.
• Automate SMS notifications for alerts based on database queries.
• Update database records automatically after notifications are sent.

Cron job triggers the workflow at scheduled intervals. Postgres node executes a query to retrieve sensor readings. Twilio node sends SMS alerts for readings exceeding the threshold. Set node prepares data for updating the database. Postgres node updates the notification status in the database.
