To switch between Celsius (°C) and Fahrenheit (°F) temperature units:
- Press and hold the button on the device for more than 5 seconds. The temperature unit on the display will change.
4.4. App Monitoring and Alerts
Once connected to the mobile app, you can:
- View real-time temperature and humidity data remotely from anywhere.
- Set custom temperature and humidity ranges.
- Receive instant notifications (APP message, SMS, or phone notification) if readings exceed the set ranges.
- Access historical data (Max/Min records within one year).
- Potentially link with other smart home devices for automated control (e.g., turning on a heater or humidifier).
This image displays the smartphone application interface, demonstrating how users can set up alerts for temperature and humidity thresholds. It also shows the potential for intelligent linkage with other smart home devices like heaters or humidifiers.
5. Maintenance
5.1. Battery Replacement
