NEMOSENSE
TECHNICAL REFERENCE MANUAL
1. Introduction
Dewesoft NEMOSENSE is a family of low power devices designed for remote monitoring. NEMOSENSE
devices acquire data, store it to an internal memory and send it to the server when connection is
available.
The initial variant of the NEMOSENSE devices released is NEMOSENSE-3xMEMS-ACC. Its physical
interface is PoE (power over ethernet). 3xMEMS-ACC stands for an integrated triaxial MEMS
accelerometer as a measurement front end. The NEMOSENSE platform allows different physical
interfaces and measurement interfaces to be released in future hardware variants.
2. Operational principle
NEMOSENSE is automatically powered up if the power is delivered to the device. On power-up, the
following sequence occurs:
1. Initialization phase - lasts only a few seconds
2. Configuration mode - device acts as HTTP server on default IP and can be configured using the
NEMOSENSE Config Tool App.
3. Operational mode - after the configuration is stored the operational mode starts which consists
of the following phases
a. Firmware upgrade mode - device tries to receive a firmware upgrade from the FOTA
server for 60 seconds
b. Measurement mode - the final mode of the start-up sequence and device stays in
measurement mode indefinitely (i.e. until the device receives a restart command from the
MQTT server or there is a power loss)
The device can only be interfaced over a TCP/IP network through its sole ethernet port.

3. Getting started with NEMOSENSE
This chapter will help you to install the software, configure your NEMOSENSE device to send the data
over TCP/IP to your or 3rd party server using the Dewesoft Historian software package. We will also show
you how to access the data using Grafana.
To follow the steps, you need the following hardware:
●your NEMOSENSE device
●Your PC
●PoE Switch or a non-powered Ethernet Switch and PoE Injector
●Ethernet CAT6 cable to connect your NEMOSENSE device to your computer for configuration
purposes
And the following software packages:
●The Dewesoft NEMOSENSE Config Tool App
●The Dewesoft Historian software (includes MQTT broker, InfluxDB database an Grafana web GUI)
Dewesoft NEMOSENSE Config Tool App
Download the Dewesoft NEMOSENSE Config Tool App from this link and unzip it.
Dewesoft Historian software
Install the Dewesoft Historian software by following the instructions here
Note: the MQTT client is already running on the NEMOSENSE device, so there is no need to
install it again. Therefore, skip the section: DewesoftX MQTT client.

Configuration mode
Connect your PC to your local network. Connect NEMOSENSE with an Ethernet cable to the same
network over the PoE* Network Switch and run the Dewesoft NEMOSENSE Config Tool App.
*In case you don’t have the PoE Switch you can inject power by using so-called PoE Injectors. 48 V is needed.
Make sure to set the IP address of your PC to the same subnet as the NEMOSENSE default configuration
address (192.168.11.XXX), for example you can set your PC’s IP to: 192.168.11.94 (same subnet but different IP
to the NEMOSENSE device).

After running the NEMOSENSEConfigApp.exe file, the following screen will appear:

TECHNICAL REFERENCE MANUAL
If the device is not in the configuration mode the device serial number and the FW version are NOT
displayed in the bottom left corner (like on the above screenshot). Unplug the device and plug it again to
restart the configuration process.
After the restart the Serial number and the Firmware version should be displayed meaning that the
device is ready to be configured.
To start the configuration and get the latest parameters, press the Get Conf button. After you’ve done
that, the Set Conf and Go to measurement buttons will be enabled.

In the top left corner the static (hard coded) IP of the HTTP server running on the NEMOSENSE device is
displayed. It can only be accessed during configuration mode:
●default configuration HTTP server IP: 192.168.11.95

TECHNICAL REFERENCE MANUAL
Note the following tabs in the config tool: Ethernet, DNS, FTP, NTP, FOTA server, MQTT and
Measurement. Those tabs allow you to select the settings of the NEMOSENSE device which will apply
when the device is in measurement mode.
The Ethernet tab offers the ability to set the device to have a static or dynamic (DHCP) IP. It also offers
the possibility to reboot the device every 24 hours if no connection is available.
The DNS tab offers configuration of several DNS servers when the devices are connected to a local
network.
The FTP tab (File transfer protocol) enables the possibility of transferring .csv files over the FTP protocol.
It is a password-protected FTP. It requires the use of a username and password, but the data transfer
itself is not encrypted.

TECHNICAL REFERENCE MANUAL
The NTP tab offers the option to have all the devices connected to the same network synchronized to an
NTP server. The IP and the port number of the NTP server need to be defined.
The FOTA server tab (Firmware over the air) it offers the option to update the device firmware remotely.
IP and Port of the FOTA server need to be defined.
The MQTT tab allows the configuration of the MQTT client running on the NEMOSENSE device. The
device communicates with the MQTT broker installed on the server. The functionality can be enabled or
disabled in the NEMOSENSE config tool app. IP and Port of the MQTT broker need to be defined.
The Measurement tab allows the selection of the supported Sample rate (S/s) options. When in
measurement mode, the device continuously acquires the data from the sensor at the specified sample
rate.
Once the settings are properly set press the Set Conf button and then press the Go To Measurement
button. The device will switch from the configuration mode to the operational mode. Configuration of
the device is no longer available.
If you need to reconfigure the device using the Config Tool app, the device needs to be restarted (i.e.
power-cycled) to enter the configuration mode.
