What is the best mobile dust monitor for community groups to use (considering rental or purchas price and difficulty of operating) that will give credible information?

Hi,

we are a startup that is building such a mobile device, connected to the smartphone and web. It would be very helpful if you could answer our problem research polls. Results will be used to focus the product and bring you the most useful solution.

Poll in relation to the mobile sensor focused on air pollution:

Please forward the polls to your family and friends.

Thank you!
