This workflow periodically checks a Postgres database for sensor readings above a certain threshold, sends a notification via Twilio, and updates the database to mark the notification as sent.

Example: A manufacturing company uses this workflow to monitor sensor data from their production equipment. The workflow checks the database every hour, identifies any sensors with readings above 70, and sends a text message to the on-duty maintenance team. This allows the team to quickly respond to potential issues and prevent downtime.

## What You Can Do
- Automated monitoring of sensor data in a Postgres database
- Sending SMS notifications via Twilio when critical thresholds are exceeded
- Updating the database to track which notifications have been sent
