Sensor configuration 

All sensor settings can be configured via a smartphone application with NFC 
(Near Field Communication) or over the air via the network server and downlink 
data to the sensor. The sampling rate, spreading factor, encryption keys, port, 
and modes can be changed. All sensor settings can be locked from the server or 
NFC to make end-users unable to read or change settings on the sensor.  

NFC Configuration 

1.

 

Download ELSYS 

Sensor Settings

 application from Google Play and install 

it on a smartphone or tablet. The device must support NFC.   

2.

 

Enable NFC on the device and start the application. 

3.

 

Place your device on top of the NFC antenna on the sensor. 

4.

 

Remove the device. Current settings will be displayed in the application. 

5.

 

Use the application to change any settings if needed. 

6.

 

Quickly tap the device on top of the NFC antenna to give the new settings 
to the sensor. Make sure that the application confirms your new settings. 

7.

 

Wait for the sensor to reboot (5 sec), indicated by the LED flashing. Sensor 
settings have been updated. 

 

See the section 

Help

 in the application for more information.
