The uRADMonitor network
The uRADMonitor project is a global array of network connected monitoring stations,
focused on continuous Environmental Surveillance. Its purpose is to generate fully
transparent open data, used to assert the quality of our environment and the impact
of various pollutants on human health.
uRADMonitor D
This is so far our most complex hardware product. It is a handheld mobile unit
designed to measure a total of six important parameters related to pollution and air
quality. It comes in a rugged aluminum enclosure that comfortably fits the palm of
your hand thanks to the side grips machined in the enclosure metal.
Connectivity
Model D is equipped with Wireless LAN connectivity, with an internal ceramic
antenna and a carefully designed window in the aluminium enclosure to allow RF
signal to escape.

Connect the uRADMonitor-D to your Wifi Internet router so data is synchronized with
the central server automatically. This allows you to access interactive charts and
stats, and do various comparisons from one target location to another, on the
uRADMonitor global map.

There is also an API that can be used to access the readings, or import them to
other systems (alarms, automated response systems, etc.).
Sensors
uRADMonitor model D uses the BME680 from Bosch to measure air temperature,
barometric pressure, humidity and volatile organic compounds, or VOC. A Sharp
photoelectric sensor is used to detect the Particulate Matter PM2.5 concentration in
air. A high quality LND712 Geiger Tube Made in the USA allows this dosimeter to
detect alpha, beta, gamma and x-ray ionising radiation.

Picture 2: uRADMonitor units on the test bench
Each Model D unit is subjected to a final test: the tested device must be in a
confidence interval of 5% in comparison to a master.
Dosimeter and Monitor
Your model can do both. Monitoring brings certain advantages over simply using a
handheld unit occasionally. First it's the capability of identifying the trend, due to
long-term measurements, and taking action in regards to the evolution of numbers
rather than not knowing how to interpret short time readings. Then with long term
continuous monitoring we get a clue even on low-level changes that often evade
portable localized readings (unless the levels are higher). Finally having an
automated system monitoring the values 24/7 results in keeping you informed all the
time, not only on occasional situations like when using a handheld for an isolated
check.
Health impact
Picture 3: Air pollution can shorten our lifespan
The purpose of the model D detector and of the entire uRADMonitor network is to
monitor chemical and physical factors that can have a negative impact on our health
or on the environment. Using its advanced sensors, the model D monitors against
the following potentially hazardous parameters:

VOC or volatile organic compounds are a class of substances that evaporate at
room temperature. Being different substances may be responsible for a broad
category of disorders, including respiratory problems, allergic or weakening
immunity in children. Some VOC ‘s are responsible for the formation of smog,
irritation of eyes, nose and throat, headaches and concentration problems. In
extreme circumstances, more severe complications can occur, such as damage to
liver, kidney and central nervous system or cancer [1].
Ionizing radiation is harmful to living organisms because it can cause damage to
cells that can result in multiple disorders, the most common of which is cancer.
Ionizing radiation is naturally occurring from cosmic and terrestrial sources, but
there are also artificial generators related to nuclear activities or x-ray devices .
Worldwide global average dose is 3.01mSv [2].
Particulate matter PM2.5 refers to small particles with a diameter of up to 2.5
microns. These particles can penetrate deep into the lungs , causing allergies,
respiratory and cardiovascular diseases .[3]

Product features
These are mobile units powered by a high capacity Lithium Ion rechargeable battery,
with a GPS receiver for location mapping and Wifi connectivity, but also with a
SDCard slot to store all readings when WLAN is not available. This not only
addresses radioactivity in a similar way to existing top-notch dosimeters, but it also
measures the air pollution, contributing with valuable data to the uRADMonitor
network. The model D also features an Alarm built in and has a touchscreen to
provide visual and audible indications, keeping you informed all the time. Using the
uRADMonitor backend infrastructure and model D's wireless data sharing
capabilities, the global readings provide useful data on pollution, its geographical
distribution, and evolution in time.

Internet connection, follow the guide below:
1.Click Settings
2.Click CFG WIFI
3.Enter SSID & KEY
4.See confirmation
Picture 5: Wifi settings
Now your Model D will connect to the given SSID for Internet access.
Webpage based configuration
The model D has an internal webserver that can be used for data access and
configuration. First, turn on your Model D unit using the start button. On your
computer search for nearby wireless networks. Connect to the Wifi hotspot
spawned by your Model D:
Picture 6: uRADMonitor local Wifi Hotspot
The SSID is uRADMonitor-XX, where XX are the last two digits of your Model D ID
(eg. 64000001) that is printed on the back of your unit, under "serial number".
uRADMonitor Wifi Hotspot password: the Device ID (eg. 64000001)
Once connected, open 192.168.4.1 in your browser. You'll see the internal webpage of
your model D. Click the WIFI link at the bottom to configure the AP where your model
D should connect to.
Picture 7: uRADMonitor D internal webpage
When done press "Change". Check the Status message to confirm the model D is
connected.

The user interface
You will interact with your model D unit using the touchscreen. This is a resistive
touchscreen, so clicks must be performed in a focused manner, unlike capacitive
screens where you use the finger. Use your nails, or a stylus.
As the unit performs multiple tasks at once, the device might sometimes be non
responsive for just a few moments. If this happens, do not express excess
pressure on the screen, better do long clicks, just until your desired action is being
recorded. Remember the LCD is sensitive, and should be treated as such.
The user interface has a titlebar, buttons, and various values displayed.
Picture 8: UI titlebar
The title bar shows the current UTC time. This is being synced automatically every
time the GPS connects, and time is kept locally by a real time clock separate circuit,
that functions even when the device is turned off, using tiny amounts of power just to
keep the time.
The first icon shows the GPS status, then there's the SDCARD symbol, the WIFI
and the speaker icon showing if the sound is enabled or muted. You can toggle
these modules in the Settings. Finally there's the date and the battery level indicator.
Offline data
All data is being recorded to the SDCARD. While using the model D offline, either
with WLAN turned off or out of your WLAN coverage area, the measurements will
be marked accordingly, and when the Internet connection becomes available, you
can use the SYNC option in the SETTINGS menu to synchronize your offline data
with the server.
The watchdog
When used as a monitoring station, most likely the unit will run unattended. There
is a watchdog mechanism that automatically reboots the unit in case of any
lockdown. This approach is a proven technique that allowed uRADMonitor units to
operated unattended for long periods of time, while providing valuable
measurements. When connected to the uRADMonitor server (network on), the
uRADMonitor D will automatically reboot if during a certain interval, it receives no
acknowledgement from the server.
The alarm
In the event of a high Radiation dose being measured or a high air pollution level,
the alarm will sound. The alarm will stop when the dose has decreased back to
normal levels.
The dashboard
The purpose of the Dashboard is to offer an interface to the uRADMonitor system,
the global data and the uRADMonitor detectors.
Using the Dashboard, you can see your connected units, add them to your account
and manage them further. This includes changing the coordinates of your
uRADMonitor unit on the map, either for better privacy or for better accuracy.
The dashboard is can also be used to access your units data.
Finally, you can use the dashboard to set automated notifications for when certain
thresholds are met.
More information is available on http://www.uradmonitor.com/dashboard
Accessing the data
You can access the data collected by your unit in multiple ways. First, you can see
the readings online, on the uRADMonitor webpage, by opening
http://www.uradmonitor.com/?open=ID (where ID is your unit's ID, just replace
accordingly)

With the embedded webserver, you can also access the data directly via your
LAN, by opening its DHCP assigned IP in your Internet browser:
Picture 10: direct access to D data via LAN
The JSON link can be used to read the data via various scripts or automation
programs. There is an online community developing such tools, here are a few
useful resources that you should checkout:

uRADMonitor API
The uRADMonitor data is released as public source, open domain. Complete
instructions on how to use the uRADMonitor API are presented in the Dashboard,
on http://www.uradmonitor.com .
Data from all units in the network is available via a RESTful API. To access the
uRADMonitor data, the following APIs have been implemented (more to be added in
the close future). Calling the following via HTTP GET:
http://data.uradmonitor.com/api/v1/devices/
will return a JSON array with all available devices, their IDs and some basic
parameters such as location, status or model type.
For a given ID, you can call:
http://data.uradmonitor.com/api/v1/devices/1200000A/
To get a list of the available sensors. Finally, knowing the ID and the sensor, call the
following to get the wanted data:
http://data.uradmonitor.com/api/v1/devices/1200000A/temperature
Here, 1200000A was just an example of a network unit.
The mobile application
At the time of writing this article, there is a mobile application for Android OS, that
can be used to access environmental data worldwide. Go on Google play and
search for uRADMonitor to download your copy.

Troubleshooting
Here are a few hints on fixing various issues when using your Model D dosimeter.
For additional help resources use the uRADMonitor forum on
www.uradmonitor.com/forum or contact us.
1.My unit doesn't start
If the battery is depleted, your unit won't start. Connect a standard USB charger,
via the USB port, and check the RED battery LED turning on. When charging is
complete, the GREEN led will turn on.
2.The unit is not visible online, nor can I access it via LAN
Make sure you've successfully configured the WIFI settings for your unit. Open
your router's admin page and check that a valid IP was allocated via DHCP. Try
pinging the IP to make sure the connection is properly setup. Check the network
and your router.
Frequently asked questions
Is my model D being calibrated?
Each uRADMonitor-D meter is subjected to a final test. The tested device must be
in a confidence interval of 5% in comparison to a master.
Can I use it outdoors?
Yes, but only taking precautions not to expose it to rain or sun. The device, like
other electronics, is sensitive to the elements, and reasonable care must be taken
to protect it.
Can I remove the SDCARD?
Yes, you can remove the card, read it on your computer, or replace it with a
different card, as long as it is formatted as FAT32, it will be recognized by the
Model D.
What is the privacy policy if the unit sends data online?
We retain no personal information associated with your unit's data online, and the
location on the map can be customized for better accuracy or better privacy,
according to your requirements. You have access to these coordinates yourself, by
using the Dashboard, on http://www.uradmonitor.com/dashboard . Additionally you
can opt to mark your unit as private.
What is a microsievert?
In physics, three types of radioactive radiation are known: alpha, beta and gamma
radiation. They differ, not only in their physical characteristics, but also in their
effects on humans. To make these three radiation types comparable in their effects
on humans, a value has been created which defines the biological effects of
radiation: it is referred to as dose equivalent whose unit is the sievert (called
equivalent dose). Based on the counted radiation pulses, the different components
of a radiation mix are converted into a common measure for the biological effect.
