Hello,
I was just wondering if there were some people iving in SF or the Bay Area hacking on Mycroft. It would be fun to meet up. I’m sort of intrigued about working with the Next bus, purple air and Fitbit apis.
Purple Air
This is information from https://docs.google.com/document/d/15ijz94dXJ-YAZLi9iZ_RaBwrZ4KtYeCy08goGBwnbCU/edit provided by PurpleAir. Saved here for reference.
Using PurpleAir data
PurpleAir sensors employ a dual laser counter to provide some level of data integrity. This is intended to provide a way of determining sensor health and fault detection. Some examples of what can go wrong with a laser counter are a fan failure, insects or other debris inside the device or just a layer of dust from long term exposure.
If both laser counters (channels) are in agreement, the data can be seen as excellent quality. If there are different readings from the two channels, there may be a fault with one or both.
In the case of a fault, the channel may be marked as flagged or downgraded (suspect or known faulty).
PurpleAir provides ways to get direct access to the data and there are a few different ways to do this.
For the simplest way to download the data, you may use the download page available at https://www.purpleair.com/sensorlist. This page provides an easy to use interface to download data based on a date range. Select the sensor(s) and dates and press download.
