uRADMonitor A3 with GSM connectivity

While a relatively new design, the uRADMonitor A3 accounts for a quarter of the total uRADMonitor network already. Introduced in 2016, it was supported by Orange in several SmartCity implementations. With an impressive number of sensors, the A3 produces highly relevant data to describe air quality in the place where it is installed. There are […]

Metal Oxide VOC Sensors

VOC sensors are nothing new to this project, we’ve used them intensively in the uRADMonitor hardware units. Back in 2015, the Bosch BME680 was integrated into the uRADMonitor model D, followed by the model A3 using the same excellent sensor. Now the uRADMonitor AIR, our first wearable, relies on the BME680 again for a low […]

A tutorial: How to compile KIT1 firmware on a Windows machine

This tutorial shows how you can compile and flash the KIT1 firmware on Windows (at least Windows 2000) without going through all the hassle of installing and using Cygwin and Eclipse. As an additional problem, there are several incompatible “make” implementations for Windows, so I decided to avoid “make” too. The AVR8 GNU toolchain does […]

Firmware upgrade for the A3 with Wifi

The uRADMonitor model A, the KIT1 and the model A3 with Ethernet have all taken advantage of various scripts and tools developed by the community which allowed direct data access over their LAN connection. You can see a few of these below: uRADMonitor weather station integration Local stats graph with uRADMonitor RRD Tool graphing Include […]

KIT1 screenless variant

Technically this is still a KIT1, and runs KIT1 firmware, but it becomes very similar to a model A unit, as it does everything a model A does. LZ1JER built one for his new weather station based on a Raspberry Pi, which is an impressive construction already: As you can see, this KIT1 variant is […]

Open Source uRADMonitor KIT1

Open Source means collaborative work, joined effort leading to extraordinary things. Recently we saw how a talented maker from Oradea, Romania pushed his KIT1 #uradmonitor unit to the limit! He used a lot of his personal time to build and document something better than the original. In the end he asked for nothing except to […]

Building the KIT1 with extra features

Last week I’ve assembled a KIT1 and posted some details about it to the forum. radhoo praised the article and asked me to share it on this blog, maybe will be helpful for the readers. So, here is an updated “copy-paste” from the original post. The diy kit is based on the v1.1.104 pcb. It […]

Air Quality Monitoring over LoraWAN

LoRaWAN is a Low Power Wide Area Network specification intended for wireless communication. The standard provides seamless interoperability of connected objects, without the need for complex installations. End devices can communicate wirelessly with a central server via radio gateways that appear as transparent bridges simply relaying the data. Picture 1: LoraWAN system diagram This opens […]

uRADMonitor KIT1.1

The uRADMonitor KIT1.1 is an Open Source Digital Radiation Dosimeter, that can be used both as a portable detector, but also as a monitoring station to upload readings to the uRADMonitor network. It relies on a Geiger tube to detect radiation. This can be build by anyone interested with minimum effort. Construction details are available […]

Weather vs Radiation readings

I’ve been running uRAD unit #12000003 here in Australia for around 12 months now and the only time I’ve really seen a solid increase in readings is during heavy rain which got me thinking, what other weather conditions affect radiation levels? To find out I purchased a cheap weather station off  eBay and set about […]

uRADMonitor KIT1

uRADMonitor KIT1 is the first open source DIY dosimeter KIT, that can be used to collect radiation measurements and push them to the uRADMonitor network. Similar to model B that is to be released later this year, the KIT1 is intended for those interested in building their own radiation devices and contribute to the uRADMonitor […]

The Compensation Capacitor

Normally, the Geiger tube delivers a sharp short pulse, with an abrupt descending path, as the quenching gas very quickly neutralises the conductive ions, and so terminating the current flow. The uRADMonitor pulses appear with a slightly rounded tip because an extra capacitor is added in the circuit, named the “compensation capacitor”. All uRADMonitor model […]

Checking the Geiger tube

The Geiger tubes used in uRADMonitor model A units are mostly the SBM-20 or the SI-29BG, both of Russian provenience, manufactured at military grade specs. Therefore they were meant to resist fluctuations over a wide interval of temperature or pressure. If a tube failure is suspected for a particular uRADMonitor unit, for example when the […]

Howto upgrade your uRADMonitor and graph local statistics

Hi everybody, My first post here to develop my answers in the forum about how to upgrade the firmware and get the local data to create some graphics. The upgrade procedure has been explained by Radhoo in a previous post, but I will add my little grain of salt.

Model A firmware upgrade guide

As a project targeting global coverage, uRADMonitor was designed with all the important features right from the start: the units are plug and play, the network settings are automated via DHCP, the location is estimated automatically based on IP and so turning the unit on is enough to have a new node on the map, […]

Powering the uRADMonitor via PoE

When I received my URAD Monitor, I was trying to think of the best placement where it would satisfy the requirement to be outdoors but still remain close to a power source.  Having worked with PoE WiFi devices before, I contacted Radu to mention a PoE solution I was considering.  Since I was able to […]

Server software improvements

The uRADMonitor project has a complex architecture, involving both hardware and software. The software level also has two separate components, one is the client firmware – the software running on the dosimeter’s microcontroller, and the other is the software running on the server. The last posts have shown a lot of progress on the hardware […]
