DRAGINO LoRaWAN 2-Channel and 3-Channel Temperature Sensor
DRAGINO LoRaWAN 2-Channel and 3-Channel Temperature Sensor provide wireless temperature monitoring for outdoor and distributed IoT applications. Both models measure temperatures from -55 °C to 125 °C with stated accuracy of ±0.5 °C, with a maximum accuracy deviation of ±2.0 °C. The D22 supports two DS18B20 temperature sensors, while the D23 supports three. LoRaWAN connectivity, temperature alarms, data logging, Bluetooth configuration and wireless OTA firmware updates support practical remote monitoring applications.
The DRAGINO LoRaWAN 2-Channel and 3-Channel Temperature Sensor are designed for applications where temperature data needs to be collected remotely and transmitted wirelessly using LoRaWAN. Their long-range, low-data-rate wireless communication makes them suitable for monitoring temperature across distributed or difficult-to-access locations.
Both models use Dallas DS18B20 temperature sensors and provide a measurement range of -55 °C to 125 °C, with stated accuracy of ±0.5 °C and maximum ±2.0 °C. The D22 has two temperature sensors, while the D23 has three, allowing the D23 to monitor one additional temperature point from a single device.
The sensors can periodically transmit temperature information through a LoRaWAN network. They also support temperature alarms, allowing users to configure temperature limits for notifications. When LoRaWAN connectivity is temporarily unavailable, the data logging function can store readings and upload them once network communication is restored.
How it works
- The DS18B20 temperature sensors measure temperature at the connected sensing points.
- The D22 or D23 processes the temperature readings and converts them into LoRaWAN wireless data.
- Data is transmitted through a LoRaWAN gateway to the applicable IoT platform.
- Temperature alarm settings can be used to identify readings outside configured limits.
- The built-in data logging function can retain readings during a temporary loss of LoRaWAN connectivity and upload the stored data when communication is restored.
- Bluetooth v5.1 and LoRaWAN remote configuration provide options for device configuration, while wireless OTA firmware updates allow firmware to be updated remotely.
Why choose this product
- Choose the D22 when two temperature measurement points are sufficient for the application.
- Choose the D23 when three temperature measurement points are required from one sensor device.
- LoRaWAN communication allows temperature readings to be collected wirelessly without requiring a wired data connection at each sensing location.
- Data logging provides additional resilience where LoRaWAN connectivity may be temporarily interrupted.
- Bluetooth configuration and remote LoRaWAN configuration simplify device setup and ongoing management.
