Done! I will add the country change option to the dashboard for the next update!

Hello Costo, thanks for the message, yet I must admit I have little success in understanding what troubles you: you can still open the map with radiation selected by default: http://uradmonitor.com/?sensor=cpm

The model A is still part of the portfolio, being one of the best products designed so far. So is the A3, which continues the radiation monitoring legacy.

Pollution affects more people (about 7million/year worldwide and about half a million per year in Europe) than radiation related incidents did during history. And the numbers are increasing considering where our society and way of living is going.

So the project tries to help more people, adding more sensors and leveraging on the mature IOT infrastructure developed so far. What’s wrong with that?

Sounds really interesting! Please share more on this, and a few pictures if you set it up!

Hello Cane,

Sorry to hear about your health issues.

The BME680 is a mems sensor, but for detecting VOC it operates on the same principle like any other semiconductor / metal oxide sensor. Read on that here: http://www.edaphic.com.au/gas-detection-encyclopedia/semiconductor-sensors/
The sensor initiates REDOX chemical reactions on a heated filament, resulting in ionised local air and as a result modified electrical resistance. A cleaner air will produce less such reactions, resulting in poor conductivity and increased resistance, while a polluted air will increase conductivity resulting in lower resistance.

Given the existence of many different gases / vapours / chemicals, any ppm would be an approximation for a particular class of substances. Their molar mass / burn rate / ionising resulting compounds and multiple other properties and complicated chemistry, make it impossible to compute an absolute ppm level, or to identify the substances.

On the other hand it offers a clear indication of changes in the air composition, and since the uRADMonitor records all data online, you have access to a history chart and you can correlate that to your condition. It will help you link the numbers to various emissions and their effect on your health.

Please have a look on the uRADMonitor A3, here. There is also the uRADMonitor INDUSTRIAL, that has 4 slots where we can install 4 sensors for 4 different gases, there’s a big list at the bottom, see it here.

That is correct. You also need to select the unit you wish to view.

Excellent! Please share a few screenshots with all this.

That robot looks awesome! Yes, for O2, the return is the percentage. As for ppm, I will get back to you on email.
