Hello,
I’ve been used loaned sensors from an EPA library, to set up in our city, over the last 14 weeks. We had a few problems setting up, (on some sensors one of the pair of sensors was not working properly) but otherwise good data for up to 7 weeks. Shortly, these sensors will be loaned to someone else. These are all associated with my email address at the moment, for enquiries. I registered them on the map at their current sites. The MAC numbers are utimately the property of the EPA. My questions are:
Do I need to hurry and set up my info retrieval today, as the sensors are being disconnected today and tomorrow? Do I set up a different project for each sensor, to start with? I suppose I am really asking on what basis do I have access to data? I will probably have more questions! Many thanks. One other thing, another member of our group has also purchased a sensor. Obviously she has set it up in her name, email etc… Can I analyse her data for her too?

Hi Sue,

It may be easiest to do a video/phone call, so we can better understand your situation, which will help us answer your questions. If you think that would be best, email us at contact@purpleair.com, and we can set up a meeting.

Ok, Andrew, many thanks. I was going to have a crack at trying to work it out now. I’ll email you tomorrow if I get stuck.
