Description
The Dragino D22-LB is a waterproof LoRaWAN temperature sensor with two DS18B20 probes for outdoor IoT applications. It records 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 also stored locally if the radio connection is interrupted and are reloaded once the network 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 seamless recording in case of network failure.
- Two Independent Measuring Points: Parallel recording at two separate locations, ideal for differential measurements or monitoring two zones with one device.
- Durable and Robust: IP66 waterproof housing with an 8500 mAh Li-SOCl2 battery for multi-year operation.
Specifications:
- Temperature Probes: 2 x DS18B20 (red and white marked), each 2 m cable, suitable for air, liquids, and surfaces
- Measuring Range: -55°C to +125°C; Accuracy ±0.5°C (max. ±2.0°C)
- Housing Operating Temperature: -40°C to 85°C
- Radio Range: EU868
Area of Application:
- Flow and return temperatures in heating and cooling circuits
- Differential measurements on heat exchangers and solar thermal systems
- Indoor and outdoor temperature in greenhouses and storage rooms
- Two-point monitoring in cold chains and process plants
