Airnow's map is slow to load, but shows smoke, air monitors (including the Purple Air ones^[footnote]), and fires all at once: https://fire.airnow.gov/?lat=37.40&lng=-122.077&zoom=10#
A less detailed, fast, static map for the SF Bay Area is available at http://www.baaqmd.gov.
Last, but not least, there is a forecast of surface-level smoke available at https://hwp-viz.gsd.esrl.noaa.gov/smoke/. I found it from https://twitter.com/NWSBayArea, which is a good source of news for the Bay Area.
[footnote]: To make the numbers match, I had to set PurpleAir to show One-Hour Averages with the LRAPA scoring. See https://imgur.com/a/d6yFtow.

Purple Air sells you a sensor that you can install, and then takes the data, displays it on their website for lots of people to view, and then presumably makes money off the data you send them? Why should you have to pay for the sensor then?

From the beginning it was important for us to give back to the community so we setup AirGradient for Education providing free tutorials and advise.
We just published our open source and open hardware air quality sensor measuring PM2.5, CO2, Temperature and Humdity. So you can build your own sensor with a small display to measure the air quality in and around your home. We call it the AirGradient DIY sensor.
Build instructions, Code and Hardware files can be found on our project page: https://www.airgradient.com/diy/
It would be great to hear feedback from you!
PS: We are also looking for schools that are interested in improving air quality to learn more about their needs and possible solutions. Please PM me for more information.

Copy/pasta to help folks:
Note: this is not my idea, but I have used it for 2 Cal fire seasons successfully.
1) Acquire a box fan
2) Acquire a large "FPR 10" rated filter from home depot
3) Duct tape filter to the out flow side of the box fan. Make sure the arrows on the filter point in the correct airflow direction.
This works dramatically well for very little dollars and can help save your lungs if air purifiers are not available or expensive.
