I think your question is not clear whether you are asking for data to be sent to you, or you want us to advise you how to collect indoor air pollutant data. 

Probably, you mean the latter. In that case you need to specify which air pollutant concentrations you want to monitor / measure and where? Are  you interested to collect indoor air pollutants data inside a school classroom, a residential house, a hospital or a mechanical garage etc. In how many indoor environment and for how long you would like to collect the data. All these depend on the resources available and the purpose of the project.

Thanks  

thank you @ Said Munir for replying me. i need data set of the listed parameters if possible. unless i need your suggestion how to collect the concentration of above listed air pollutant in residential house where household activities like oil-cooking, smoking, spraying can change the level of air quality. so i assumed that by using specific/related sensor for each components and for one two week period. 

Dear Dawit Uta,

Sorry I dont have indoor air quality dataset. Even if someone has a dataset, it will be different from the locality where you want to monitor indoor air quality. So I suggest you collect your own data, probably using some portable instruments, which are cheaper and easy to use. 

Ideally the data should be for a whole year to account for seasonal variations (i.e. how pollutant levels vary in different seasons: winter, summer, autumn and spring). However, if you dont have time and resources to collect data for the whole year, then you may collect data for a shorter period, let say a month or two.

Best of luck 

Dear Said Munir,

thank you very much for your clarification. i will do as what you have suggested me and i need you suggestion in any difficulty!!! 

You are welcome anytime.
