Dragino D20S-LS-EU868 Solar LoRaWAN Temperature Sensor for Soil Applications

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

Key Features:

• LoRaWAN 1.0.3 Class A Protocol: Offers long-range communication with low energy consumption and high interference immunity.
  
• Bluetooth v5.1 & OTA Support: Simplifies parameterization and firmware updates.
  
• Temperature Alarm and Datalog: Threshold-based immediate notifications and seamless recording in case of network failure.
  
• Soil Probe for Buried Use: Robust design for permanent installation in soil, concrete, or road surfaces.
• Solar Powered for Autonomous Outdoor Use: IP66 waterproof housing with integrated solar panel and 3000 mAh Li-Ion battery for several years of low-maintenance operation.
