Dragino D20S-LB-EU868 LoRaWAN temperature sensor for soil applications

The Dragino D20S-LB is a waterproof LoRaWAN temperature sensor with a ground probe, designed for permanent installation in soil, concrete, or pavement. It records temperature values via an external DS18B20 probe with a 2 m cable and transmits the data energy-efficiently over the LoRaWAN network to the IoT platform. Thanks to its datalogging function, measured values are stored locally even when the radio connection is interrupted and are reloaded once network connectivity is restored.

Key Features:

• LoRaWAN 1.0.3 Class A Protocol: Provides long-range communication with low power consumption and high interference immunity.
  
• Bluetooth v5.1 & OTA Support: Simplifies parameterization and firmware updates.
  
• Temperature Alarm and Datalog: Threshold-based instant notifications and continuous recording in case of network failure.
  
• Ground Probe for Buried Installation: Robust design for permanent installation in soil, concrete, or pavement.
• Durable and Robust: IP66 waterproof casing with an 8500 mAh Li-SOCl2 battery for multi-year operation.

Specifications:
