Thanks to uRADMonitors generosity and determination to beat air pollution I am going to give away 10 uRADMonitor SMOGGIE.
I am searching for Volunteers all around the world who are willing to install an Air Quality Monitor in their backyard or balcony or window or any other outdoor environment in order to build a better air quality network and to help you raise awareness in your neighborhood/ community.
Wearable or portable devices are not so often considered important in order to protect yourself from air pollution. Most ads claim that we spend 90% indoors and we need an indoor AQ Monitor which is true but we also move around we go to work or we visit friends and family who don’t have an AQM in their house or simple they are not aware of the problem.
Here comes the new Atmotube PRO a small portable AQM equipped with a laser scattering PM1, PM2.5 and PM10 sensor. It also features a VOC sensor and a complete weather station with humidity, temperature and barometric sensor.

A new update for the DIY Air Quality Monitor is available with some cool new features. The new version v0.2 has the following features.
Recently, I travelled to Egypt and I had the pleasure to visit and see many fantastic and immense monuments like the Great Pyramid of Giza, the Abu Simbel temples and many others. A fantastic journey through ancient Egypt which literally transfers you to this great ancient civilization.
It rarely rains in Egypt and the temperature in summer can easily reach 48ºC/118ºF. That said, the Sahara desert plays an important role in the climate and air quality of the country. Particulate Matter is the main natural air pollutant and impossible to combat.
In my previous post I presented the version 0.1 of my DIY Air Quality Monitor which uses a Nitrogen Dioxide sensor. In this post I am going to analyse the Nitrogen Dioxide NO2 sensor which is made by Spec-Sensors DGS-NO2 968-043 .
In most cases the sensor isn’t calibrated which means that we have to set a zero point in order to get more accurate measurements. The company can calibrate it for you in a special chamber but you have to pay extra. In order to calibrate it on your own you have to be in a clean environment – without the presence of NO2 or NO or O3 – and then follow the instructions below which I have taken from the datasheet.Read More »
Have you ever been in a situation where you wish you had had a device tailored to your needs? Over the years I have reviewed various Air Quality Monitors but each time they lack something which will make them unique to me. Don’t get me wrong each device has its features and characteristics, some of them are amazing and some of them not very useful. As a result, I decided to build my DIY AQM. I couldn’t have done it without Electronza and Teodor Costachioiu help with coding, he is a brilliant coder/engineer. I absolutely recommend you to check his blog you will find a lot of interesting projects.
The idea of having an Air Quality Monitor anywhere you go seems good especially when you can have 9 sensors with you. So here is a tip on how to convert a stationary IoT indoor AQ monitor to a portable one, in this case I will demonstrate it with the uHoo because I really want to measure some NO2 and O3 concentrations in some busy spots of the city.
There two ways to do that, one of which isn’t easy but bear with me.
Over the years, I have reviewed some very good face masks on See The Air like the Cambridge Mask and Vogmask. The only backward is the price especially when you have to buy them frequently because you wash them often and you wear them a lot. There is a solution by using masks such as the AirGo which allows you to chance the filters and the neck warmer is durable and washable and the O2 Canada Respirator which allows you to change filter easily. However, I wanted to try a cheap and lightweight face mask for the summer which will cost around $3 and it will have the ability to use exchangeable filters because I want to be able to wash it once a week.
Over the past few years, I have been tweeting and posting messages on social media platforms about air quality and pollution issues around the globe and I have noticed that the more severe the message the greater the response from people (likes and/or retweets). The same technique is being used by newspapers and magazines to achieve greater impact.Read More »
Here are all the available IAQ Monitors on the market. This time and after your help I have included many more information in a Google Spreadsheet document which you are going to appreciate a lot, such as website links and whether the device has been reviewed on my blog or not yet. There are so many devices out there but they all lack innovation and they all offer exactly the same technologies. Companies had better hear users feedback!
