Commissioning

📢 Please note that when using knives or other sharp objects, the case or electronics may be damaged.

Open the sensor on the tab provided for this purpose (in the picture at the bottom). Use a sharp object carefully if necessary.
Insert the cells now To achieve the specified runtimes and the performance specified in the datasheets, the following primary cells are allowed:
1. For LoRaWAN® and mioty® sensors
  - Energizer® Ultimate Lithium Batteries – AA
  - VARTA ULTRA LITHIUM Mignon AA
2. For cellular sensors (NB-IoT)
  - Energizer® Ultimate Lithium Batteries – AA
  - VARTA ULTRA LITHIUM Mignon AA
  
  Each sensor requires 4 cells.
The sensor is now open. If you have a NB-IoT sensor and you want to insert your own SIM card, insert the SIM card now.
If the sensor is now open, press the switch to start the device. After flipping the switch, the sensor starts, the 3 LEDs on the front flash and you can hear a sound sequence. The sensor then performs a measurement. The LED light shows you the result.

NFC parameterization and position of the NFC tag

Activation takes place via an NFC app. A smartphone is required for this. The app can be downloaded from the respective app stores. Just search for “Sentinum LinQs” and download the LinQs app.
Locate the tag on the sensor first and then the reader on your device. The position of the NFC tag can be found in the following pictures.
