Payload Decoder Apollon-Q Series

1. NFC Setup and Location of the NFC Tag

Activation is performed via the NFC app. A smartphone is required for this. The app can be downloaded from the respective app store. Search for Sentinum LinQs and install the application.

First, locate the NFC tag on the sensor and then the NFC reader on your smartphone. The position of the NFC tag is shown in the following figures.

Position des NFC-Tags — Figure 2: Position of the NFC tag on the sensor.

Open the app and activate the sensor. In the start menu, select the "Activate Sensor" button and hold your smartphone up to the sensor's NFC tag.

Figure 3: Activating the sensor via NFC.

Note:
When the sensor is activated, you'll see "Sensor Updated!". You can then continue activating additional sensors.
