Description
The Dragino D22-LS is a waterproof LoRaWAN temperature sensor with two DS18B20 probes for outdoor IoT applications. It measures two independent temperature values in parallel and transmits the data energy-efficiently via 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 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.
- Two Independent Measurement Points: Parallel data collection at two separate locations, ideal for differential measurements or monitoring two zones with one device.
- 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.
Specifications:
- Temperature Probes: 2 x DS18B20 (marked red and white), each with 2 m cable, suitable for air, liquids, and surfaces
- Measurement Range: -55°C to +125°C; Accuracy ±0.5°C (max. ±2.0°C)
- Operating Temperature Housing: -40°C to 85°C
- Radio Range: EU868
Application Area:
- Flow and return temperature in heating and cooling circuits
- Differential measurements on heat exchangers and solar thermal systems
- Indoor and outdoor temperature in greenhouses and storage rooms
- Long-term monitoring in remote locations without maintenance access
