1. Wprowadzenie
The Dragino T68DL Temperature sensor is a Long Range LoRaWAN Sensor with an IP68 waterproof rating. It is designed to allow users to send data over extremely long ranges, providing ultra-long range spread spectrum communication and high interference immunity while minimizing current consumption. This sensor is ideal for professional wireless sensor network applications such as irrigation systems, smart metering, smart cities, and building automation.
The T68DL features a built-in 2400mAh non-chargeable battery, offering a lifespan of up to 10 years*. It is fully compatible with the LoRaWAN v1.0.3 Class A protocol, enabling seamless operation with any standard LoRaWAN gateway.
A key feature of the T68DL is its Datalog capability. This allows the device to record data even when network coverage is unavailable, ensuring that no sensor readings are missed. Users can retrieve this stored data later.
*The actual battery life depends on the frequency of data transmission. Refer to the battery analyzer chapter (if available in full documentation) for more details.

7. Konfiguracja
To set up your Dragino T68DL sensor:
- Rozpakować: Carefully remove the T68DL sensor from its packaging.
- Początkowa aktywacja: The sensor is typically shipped in a low-power mode. Refer to the specific product documentation or the manufacturer's website for details on initial activation, which may involve pressing a button or connecting to a configuration tool.
- LoRaWAN Configuration: Configure the sensor with your LoRaWAN network server details (e.g., Device EUI, Application EUI, Application Key). This is often done via AT commands through a serial interface or remotely via LoRaWAN Downlink commands.
- Umieszczenie: Mount the sensor in the desired location, ensuring it is within range of your LoRaWAN gateway. The IP68 rating allows for outdoor and harsh environment placement.
- Weryfikacja: Verify that the sensor is successfully joining the LoRaWAN network and transmitting data. The tri-color LED can provide status indications during this process.
8. Instrukcja obsługi
Once configured and deployed, the T68DL operates autonomously, periodically transmitting temperature data to your LoRaWAN network server. Key operational aspects include:
- Transmisja danych: The sensor will transmit temperature readings at intervals defined during configuration.
- Rejestracja danych: If network connectivity is lost, the sensor will store data internally. This data can be retrieved once connectivity is re-established or through specific commands.
- Wskaźniki LED: Observe the tri-color LED for operational status. Consult the full product manual for specific LED patterns and their meanings.
- Zdalna konfiguracja: Parameters such as transmission interval or alarm thresholds can be adjusted remotely via LoRaWAN Downlink messages from your network server.
9. Konserwacja
The Dragino T68DL is designed for low maintenance due to its long battery life and robust IP68 enclosure. However, consider the following:
- Czas pracy baterii: The internal 2400mAh battery is non-chargeable and designed for up to 10 years of operation. Monitor battery levels via LoRaWAN payloads if supported by your network server. Battery replacement is not user-serviceable.
- Czyszczenie: Periodically clean the exterior of the sensor, especially if deployed in dusty or dirty environments, to ensure optimal performance and longevity. Use a soft, damp płótno. Nie używaj ostrych chemikaliów.
- Aktualizacje oprogramowania układowego: Sprawdź Dragino website for any available firmware updates. Updates can improve performance, add features, or address issues. Firmware upgrades are performed via the program port.
- Zagadnienia dotyczące ochrony środowiska: While IP68 rated, avoid prolonged submersion beyond specified limits or exposure to extreme physical stress.
10. Rozwiązywanie Problemów
If you encounter issues with your T68DL sensor, consider these common troubleshooting steps:
- Brak transmisji danych:
- Check LoRaWAN gateway connectivity and range.
- Verify LoRaWAN network server configuration (Device EUI, App EUI, App Key).
- Ensure the sensor is activated and not in a sleep mode.
- Check the tri-color LED for error indications.
- Niedokładne odczyty:
- Ensure the sensor is not exposed to direct sunlight or other localized heat sources that could skew readings.
- Verify the sensor's operating range (-40 ~ 85 °C) is not exceeded.
- Datalogging Issues:
- Confirm the datalogging feature is enabled in the sensor's configuration.
- Ensure sufficient internal memory for storing data.
- Problemy z łącznością:
- Relocate the sensor or gateway to improve signal strength.
- Check for potential interference sources.
For persistent issues, consult the detailed technical documentation available on the Dragino website or contact Dragino support.
11. Wskazówki użytkownika
- Optymalizacja czasu pracy baterii: While the battery lasts up to 10 years, frequent data transmissions will reduce this. Configure the transmission interval to balance data granularity with desired battery longevity.
- Planowanie sieci: Before deployment, perform a site survey to ensure adequate LoRaWAN coverage, especially for critical applications.
- Pobieranie danych: Regularly check your LoRaWAN network server for data from the sensor. Utilize the datalogging feature as a backup for periods of network instability.
- Bezpieczne mocowanie: Use the integrated mounting tabs to securely fasten the sensor, preventing accidental dislodgement or damage, particularly in outdoor or industrial settings.
