Nov 2019: a US radio host claims China nuked South China Sea, citing #uRADMonitor data as proof. Pentagon called it "silly fiction". No quake, no anomaly, no event. One number without context proves nothing. Think. Ask questions. Challenge assumptions:

New on uRADMonitor: Cities. A dedicated air-quality page for your city, built automatically from live sensor data. Current readings + 30-day trends for PM2.5, ozone, #noise, #radiation and more. Find yours: uradmonitor.com/introducing-…
A @uRADMonitor study on #airquality in schools. Two MODEL A3s, 150K readings:
- classroom CO₂ above 1,500 ppm for 83% of winter lessons
- airing at lunch cut it by 700 ppm in 40 min
- the VOC sensor sees every cleaning
Case study Dumbrăvița, Romania:

Probably the most advanced uRADMonitor station on the network right now. Jan Pagac bridged 3 devices (GQ RadonPro + AirGradient + Ecowitt GW1100) through Home Assistant to uRADMonitor via EXP/DIDAP:

#uRADMonitor #HomeAssistant #OpenSource #Radon #IoT
Community build: ESPHome bridge connecting a RadiationD-v1.1 (CAJOE) Geiger counter to both Home Assistant and the #uRADMonitor network via EXP/DIDAP. ESP8266 + 3D-printable enclosure, all on GitHub.

The #uRADMonitor KIT2: an open-source portable Geiger counter built for students. SBM20 tube, ESP8266 WiFi, OLED display, LiPo battery, 3D-printed enclosure. Born out of Erasmus+ student workshops, everything on GitHub. #OpenSource #GeigerCounter #Erasmus uradmonitor.com/uradmonitor-…
New interview with @localhaze on building #uRADMonitor from a single #radiation sensor in 2012 to a global network on every continent.

uRADMonitor retweeted
2011: radiation detectors vanished from shelves worldwide. Radu Motișan's answer was to build his own - one that reported straight to the internet, before the term "IoT".
@uRADMonitor now spans every continent. Read our interview with @RaduMotisan here: localhaze.humanlogic.com/202…
A small world indeed, but much better when working together.
Oh, judging by the photo, the #GGreg20_V3 is being used in this project. Thank you for choosing our product. Now the @GGreg20_V3 data is also available on the legendary @uRADMonitor network!

Back to Craiova for the third time! 🛠️ Students at the University of Craiova built, programmed and deployed their own #AirQuality #IoT #sensors in just two days . 10 new #uRADMonitor #SMOGGIE units now heading home.

☢️ A working PoE #radiation sensor on ~30 lines of YAML. Pavel used a SBM20 tube, GGreg20_V3 frontend, Olimex ESP32-POE-ISO, one cable for power & data. No custom firmware, just stock #ESPHome, with #HomeAssistant uploading to #uRADMonitor network. 🧵 uradmonitor.com/a-poe-radiat…
Fresh on the uRADMonitor map:
⏱️ History slider now works across whole regions, not just single cities : rewind 24 h of air quality at country scale.
📊 Compare sensors side by side: pin a few, see their trends overlaid on one chart.

A sneak peek at something new we’ve been working on - the KIT2: #opensource #IOT portable environmental sensor with a #Geiger #radiation counter, temperature, pressure and humidity sensors, an LCD display, a rechargeable battery, and Wi-Fi connectivity.
More to come.
The uRADMonitor Notifications keep the network alive: they are how a disconnected sensor gets noticed and brought back online, so they cannot be switched off. You can, however, choose how often you receive them: uradmonitor.com/dashboard
uRADMonitor was built to be modular and connect with other technologies, so we’re always glad to see projects like David’s, bringing sensor data straight to a phone widget: uradmonitor.com/my-android-w…

No government funded this. You did. And others like you. One sensor at a time. Across 76 countries, over a decade. #IoT #global #monitoring
Thank you! uradmonitor.com/network/
#uRADMonitor 3rd on @f6s top #environmental companies for July. Not bad. Not bad at all. #IoT #sensors #airquality
Erasmus+ Students at the Emil Racoviță Theoretical High School in Vaslui, Romania, built a solar powered smart bench with #airquality #uRADMonitor sensors: uradmonitor.com/solar-bench-…
A 2017 #uRADMonitor MODEL A3 /w #radiation sensor failed after almost 10 years. Most people would replace it. Adam repaired it instead and brought it back to life. 🔧⚡
