EGYPT – Air Pollution

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.

See The Air AQM v0.1 – NO2 Analysis

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 .

Calibrating your sensor.

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 »

SeeTheAir AQ Monitor v0.1

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.

uHoo a Portable AQM?

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.

Cheap Face Mask, Worth it?

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.

Air Pollution – Wrong Approach

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 »
