With asthma and two young children, Knoy said she wasn’t satisfied that readings in Santa Rosa and Sebastopol reflected what the air was like in her city. They included Cotati resident Sandra Knoy, who decided to buy a $230 PurpleAir monitor and join the network. ![]() The number of local data points increased over the last several weeks as people - hungry for data to confirm what their eyes saw - realized there weren’t sensors in their neighborhoods. Sonoma County school officials even tapped the site to decide whether the air was too toxic to hold class.

This actually wouldn’t be so bad if I could stay logged in. The only way I can view my indoor sensor on the map is by logging in using my Google account. Either “read_key=” doesn’t work or I am not understanding how it is intended to be used. This had no effect in fact, all the parameters beginning with “?” disappeared from the URL in the browser’s address bar. I tried editing the URL to change “key=” to “read_key=”. (I also have an outdoor sensor that is public the map does show that.) This link goes to the correct location on the map, but it doesn’t show my private sensor. The link that I was sent during registration contains “key=”. This information appears as if it might be useful, but I haven’t been able to get the “read_key=” method to work for accessing a private sensor.

The sensor index that follows will be selected. Only one sensor index can be placed after “select=”. Parameters you can use are “select=”, “show=”, and “key=”. You can separate items with a pipe ‘|’ symbol. Multiple sensor indexes and read keys can be added to custom a URL to customize it to your liking.
