1. Product Introduction
S2100 LoRaWAN Data Logger can collect data from different types of sensors and transfer
the data through LoRaWAN network. If you have deployed sensors that are not based on the
LoRaWAN network, then with our LoRaWAN Data Logger, you can change them into
LoRaWAN-based sensors and use the LoRaWAN network to transfer data. You can easily
enjoy the advantages of LoRaWAN technology such as low power consumption and long
transmission range, without affording the cost of changing the sensors you are using.

4.2.2 Power supply options of sensor
Data Logger supports two power supply modes:
Mode
Description
Built-in Battery
When the Data Logger and sensors only powered by internal
battery. The datalogger only support 5V or 3V sensor probes.
External 12V DC
If some cases, the sensor probe needs a higher power source
which the internal battery cannot last for long time.
An external 12V power source could be the main power supply,
and the internal battery works as a backup power source when
the 12V power outage happen.
When using external 12V power supply, it is recommended that
working together with the junction box to make sure the
waterproof covered.

4.2.3 How to install external 12V DC
When your sensor needs 12V power, the internal battery will not be able to feed the sensor.
Therefore, an external 12V power supply is required.
Take the SenseCAP ONE Weather Station as an example.
1) Prepare the12V DC adapter, Junction box, and 4-pin wire.
2) Wire the RS485-A, RS485-B and GND and external 12V input to the green terminal.

3) Put the device circuit board back to enclosure, and make sure the waterproof rubber is
well assembled.
4) Wire to the terminal of the junction box.

5) Connect the sensor wire to the junction box.
6) Connect the 12V DC adapter to the power supply.
7) To complete the assembly.

8) Tighten the screws and screw caps to check the waterproofing. If the wire diameter
is too thin, add waterproof tape for winding.
*Note: When assembling the device, it is necessary to install the waterproof pad of the Data
Logger and the adapter box, and tighten the screw cap and screw, otherwise the waterproof
effect of the device may be affected!
If the wire diameter is too small, it can be wrapped with waterproof tape, as shown below:
