4. Operating Instructions
4.1. Remote Monitoring
Once your Proteus AMBIO sensor is set up, you can monitor temperature and humidity data remotely through the Proteus web portal. Access the portal from any web browser on your smartphone, tablet, or computer. The dashboard displays real-time readings and allows you to adjust settings as needed.

4.2. Alert Configuration
You can customize alert thresholds for both temperature and humidity. When readings fall outside your set range, the sensor will trigger alerts. Alerts can be sent to multiple email addresses and phone numbers via text message. The built-in buzzer will also sound locally.
