Function and purpose
The LR490 Dual sensor is a high-quality wireless temperature and humidity sensor. By connecting to the LR800 Gateway & Server or 3rd party LoRaWAN gateway, you can measure temperature and humidity parameters anywhere in the area.
The Dew point is easily calculated using the temperature and humidity parameters of the LR800 inside the Vutlan web interface.

Add a sensor to the LoRaWAN network
This sensor can be added to LR800 Gateway & Server.
Support for 3rd party gateways will be added soon.
First, follow the instructions in the article: Add a new LoRaWAN sensor
After the last step (inserting the batteries into the sensor), the sensor begins the activation process in the LoRaWAN network.
This process is indicated by a rapid flashing of the red LED.
If activation is successful, the red LED will flash continuously.
If there is no continuous flash, the connection attempt to the network was unsuccessful and will be retried in a few seconds.
Normal data transmission from the sensor is indicated by a short flash of the red LED.
After inserting the batteries, the sensor ignores alarms from the Shock sensor and the Case opening sensor for 5 minutes. This allows time for the sensor to be safely installed in its operating location.
Status LED indication
LED indicator | Sensor status |
|---|---|
Quickly flashing | Begins the activation process |
Remains steadily ON for 3 seconds | Activation or reconnection is successful. |
Does not remain steady ON | Activation unsuccessful. |
Flashed one time | Normal data transmission (uplink). |
