What to measure, which instruments to use and how to read the results. A practical guide to measuring air pollution indoors and outdoors, from reference stations to low-cost sensors.
September 8–9, 2026, Craiova: For the third time, following the events in 2022 and 2023, the University of Craiova becomes the venue for a hands-on air quality sensor workshop, this time as part of the Interreg ROBG PROMISE-Hard project (000299). uRADMonitor founder Radu Motișan returned to the Physics Department for a two-day extended workshop, guiding […]
The Project Students at the Emil Racoviță Theoretical High School in Vaslui set out to do something most schools wouldn’t attempt: design and build a smart solar bench from scratch. They built it, wired it, and equipped it with electronics and the result is a functional piece of outdoor furniture that doubles as an environmental […]
What to measure, indoor or outdoor, which connectivity, how accurate. Seven questions that help you choose the right air quality monitor for a home, a school or a city.
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 […]
Having almost 1000 SMOGGIE units deployed, makes this one of the best designs we came up with. It’s likely the max we could do in terms of IOT sensors with the existing technology, by optimising all aspects but with no compromise to data accuracy. This was rewarded last year in Paris, where uRADMonitor took two […]
Breaza is a town located in the sub-Carpathian area, at an altitude of 380–450 m, on a terrace located at a height of 50–60 m above the Prahova riverbed. Some of the people here, have chosen to settle in a quieter area and with a cleaner environment.This direction was perhaps a contributor factor to an […]
When I designed the “uRADMonitor SMOGGIE”, I was trying to find a solution for the uniformity problem of the uRADMonitor network. The sensors were present mainly in developed areas, leaving in the dark various other places on Earth. The resulting map matched the Facebook Graphs or the Electric Lights viewed from Space. I think we […]
This Guide is written for MacOS users, however, there is a dedicated Firmware Update Guide for other platforms. What do we need?1. Smoggie hardware. (Smoggie-PM, Smoggie-CO2, and Smoggie-Gas)2. The provided USB cable (or any usb cable that also has data transfer capability).3. The new firmware. For this contact support (send the model and the serial number printed on the device or […]
From day one, uRADMonitor aimed to give people open, comparable and uniform environmental data across large areas. Some time with this project and it became evident that spreading the network uniformly across the world is going to be a challenge. This was mainly due to economic differences of the various countries in the world. Simply […]
The PMSA003 is one of the smallest laser scattering particulate matter sensors available on the market today. The manufacturer, Plantower, has built a reputation with their robust sensors widely used in applications worldwide. Various labs tested their performance against reference stations and came to positive conclusions in regards to the accuracy of these sensors. Some […]
The initial article about Smoggie firmware upgrade uses a Python script to install the firmware. This can be too much for the usual Joe user, so here is, I hope, a simpler way. What do we need?1. Smoggie hardware. (Smoggie-PM, Smoggie-CO2, and Smoggie-Gas)2. The provided USB cable + a Windows-running computer.3. The new firmware. For […]
Smoggie is the recent uRADMonitor product based on a versatile compact platform that can handle multiple sensors, making space for several Smoggie based products depending on what they measure. Currently the list includes the Smoggie-PM, the Smoggie-CO2 and the Smoggie-GAS for Particulate Matter (PM1/PM2.5/PM10), Carbon Dioxide and toxic Gases. They all share similar form-factor and […]
The uRADMonitor network reached 1k units worldwide back in September 2018 during the ASIC conference in Oakland US. It was becoming clear that Air Quality monitoring is a major concern with various implementations happening thanks to recent advancements in sensors and IOT technologies. Our portfolio of products already covered multiple scenarios both in terms of […]
