3. Assemble the Daviteq LoraWAN Exd Pressure device:

Note: Only re-use housing, antenna for converting from Sigfox device to LoraWAN device. DON’T re-use the Sigfox mainboard and pressure sensor.

  • Step 1: Apply thread lock glue to the connection thread and screw the new pressure sensor to the housing by turn clockwise.

Warning: Do not use to too much glue as it will take too long to dry and leak to the mainboard. Recommend using 2-3 drops of glue.

  • Step 2: Select correct LoraWAN mainboard for the sensor in the step 1:
    - 10 bar new sensor will be installed with LoraWAN mainboard having item code on the main board label of WSLRWEX-PPS-10-01
    - 100 bar new sensor will be installed with LoraWAN mainboard having item code on the main board label of WSLRWEX-PPS-100-01
  • Step 3: Note out the serial number on the selected LoraWAN mainboard label for later usage in labelling step.
  • Step 4: Screw the antenna cable on the LoraWAN mainboard to antenna and plug socket of sensor cable to the socket on the LoraWan mainboard.

Warning: Arrange the wires neatly to avoid the wires being stuck.

4. Stick labels on the housing of Daviteq LoraWAN Exd Pressure device:

There are 4 types of labels for the LoraWAN Exd Pressure device: 
1 x LoraWAN label,
1 x Device information label
1 x Magnet reed-switch label
1 x Manual QRCode of Daviteq LoraWAN Exd Pressure firmware3 device label 
And 4 types of label and LoraWAN mainboard in the package.

  • Step 1: Screw the housing cover tighty then stick the LoraWAN label vertically. The direction of the label as Figure 4.1.

  • Step 2: Stick the device information label at the position at Figure 4.2.

Note: Make sure the serial number on the label is the same as one on the main board label. The serial number on the mainboard label is noted out in step 3 of section “3. Assemble the Daviteq LoraWAN Exd Pressure device”

The the device information label is next to sensor mounting semi-circular hole.
