Hi all, Back in 2021 I started off with a very simple Heltec wifi kit 32 and since then I’ve been happily logging data using DIDAP (old method EXP1) protocol with a very basic interface and switched over to an Espressif ESP32 wrover-e with a little more advanced version thanks to it’s hardware specs and […]
A uRADMonitor MODEL CITY leaves the rooftop behind, mounts on a sailboat’s pushpit, and starts feeding air quality data into the OceanoVox ocean-observation network. For over a decade, the uRADMonitor network has grown one fixed station at a time , mounted on rooftops and walls across 76 countries. Now this one moves. Off the Atlantic […]
We are excited to announce that uRADMonitor CITY now supports SDI-12, the industry-standard serial digital interface widely used in environmental monitoring and data acquisition. With this update, uRADMonitor CITY can be connected directly to dataloggers, PLCs, weather stations, and other SDI-12 compatible equipment, opening the door to deployments in scientific, industrial, and municipal monitoring networks […]
Fireworks are launched by a small rocket that explodes in the sky, creating brilliant colors from burning metallic salts (e.g., strontium for red, barium for green, copper for blue) along with loud bangs and clouds of smoke. The explosion releases soot, chemical residues, heavy metals, burned paper, and large amounts of fine particulate matter (PM2.5 […]
As we wrap up 2025 with this end-of-year article, we’re thrilled to celebrate a year of impressive hardware advancements at uRADMonitor, pushing sensor precision and network reach to new heights. Above all, peace has been the greatest gift, creating the ideal conditions for creativity and progress to thrive, and 2025 delivered that, at least for […]
What Is Indoor Air Pollution? Indoor air pollution refers to the presence of harmful substances within indoor environments, often resulting from various sources like cooking, heating, cleaning products, and building materials. Prolonged exposure to these pollutants can lead to a range of health issues, including physical and cognitive issues, contributing to the phenomenon known as “Sick […]
We are excited to share the latest deployment of uRADMonitor SMOGGIE-HEAT sensors in Vietnam, as part of a collaborative research initiative led by the prestigious Institut Polytechnique de Grenoble (INP Grenoble). This marks another important step in our commitment to supporting global scientific research and innovation in air quality monitoring. About INP Grenoble Located in the […]
I am a researcher working on topics related to aerosol composition and dynamics, in particular the measurement and analysis of PM2.5 and PM10 in urban environments. In my work I have been using data from uRADMonitor devices to obtain a better understanding of air quality in Romanian cities. Low-cost sensors vs. reference grade equipment Low-cost […]
Advances in optical particulate matter sensors have opened the door for the existence of air quality monitoring networks using low cost sensors. The reduced cost allowed the spread of thousands of IOT automatic sensors, offering an unprecedented spatial resolution, the so called “hyperlocal air quality monitoring”. While signifiant technical advances have been made to offer […]
We know well that traffic is a major source of pollution. But what does that mean, actually? First thing that pops to our minds is, of course, the exhaust gas, that contains carbon monoxide, nitrogen oxides, and particulate matter, all of which can have harmful effects on human health, especially with long-term exposure. It’s generally […]
uRADMonitor technology in partnership with DIM Transilvania Group contributed to the first scientific collaborative research of hairdressers exposure to respirable particulate matter (RPM) inside minority-owned hair salons in the state of Maryland, US. The report was conducted in alliance with leading experts from Johns Hopkins Bloomberg School of Public Health, School of Public Health at […]
We are extremely pleased to announce that uRADMonitor in partnership with DIM Transilvania Group have established a collaborative research program with the Washington, D.C.-based George Washington University (GWU)’s Milken Institute School of Public Health and the School of Engineering and Applied Science. The project’s goal is to create a Washington, D.C. Air Quality Monitoring Network […]
A high concentration of CO2 is nothing but re-breathed air that can be a carrier of pathogens. Whether we are talking about schools, hospitals, residences, cinemas, offices… all these are closed spaces where the human presence generates carbon dioxide (CO2). This is a gas that is emitted when we exhale. The high level of CO2 […]
Radu Motisan has a dream to give the world a view on what is happening in your surrounding environment and how this could influence your health. In my own professional life, I’m involved as a consultant in IOT data gathering and processing and I design and deploy solutions for organizations with whom I share that mutual interest: […]
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 […]
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 […]
Every gain comes at a price, and so the comfort of technology claims its cost at some other end. For nuclear energy – what it gives is known, modern living conditions, heating, illumination, transportation and all in one the civilised world as we know it. Yet what it takes sometimes remains in the shade, like […]
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 […]
The uRADMonitor project started with a single network connected automated dosimeter, that quickly proved its usefulness and spawned into a global scale, full fledged monitoring network, covering all major continents. At the core of the entire infrastructure are the low power automated dosimeter units, at the moment of this article available as the uRADMonitor model […]
Richard Prettyman, August 2014 Background A close correlation between gamma count rate at ground level, and soil derived Rn-222 flux has been demonstrated in work which has also studied the effects of meteorological and diurnal factors on Rn out-gassing and hence gamma count rate (Szegvary et al, 2007). Under conditions of settled weather with no […]
The Geiger tube is a gaseous ionization detector that uses the Townsend avalanche phenomenon to produce an easily detectable electronic pulse from as little as a single ionising event due to a radiation particle. It is used for the detection of gamma radiation, X-Rays, and alpha and beta particles. It can also be adapted to […]
