Does Purple air have an API?

Providing a way to programmatically interact with PurpleAir data, the PurpleAir Sensor API is based on REST principles employing the following HTTP methods: GET : Returns information.

Does PurpleAir have an API?

PurpleAir provides access to our real time data in a JSON format. … Accessing data directly from Thingspeak: Another way to get the data is to use ThingSpeak.com and to do this, you will need the API Key and channelID.

How does PurpleAir get its data?

Users of PurpleAir can toggle between real-time data and readings averaged over the last 10 or 30 minutes. The data comes from the commercial sensors the company sells, which members of the public install on porches, yards and other neighborhood sites.

How do I get a PurpleAir API key?

Documentation is at https://api.purpleair.com and please email [email protected] for keys if you want to play. It includes a cool “groups” feature where you can create your own lists of sensors that you are interested in.

Is PurpleAir a reliable source?

For the national data set of sensors collocated with regulatory-grade monitors, results show that PurpleAir sensors, when corrected, accurately report NowCast AQI categories 90% of the time as opposed to uncorrected PurpleAir data, which are accurate only 75% of the time.

What does Lrapa mean on PurpleAir?

LRAPA PurpleAir Monitor Correction Factor History. In 2017 Lane Regional Air Protection Agency (LRAPA) began investigating the idea of using low-cost particulate matter (PM) sensors to supplement our PM2. 5 monitoring network and as a possible tool for use by citizens concerned about the PM levels in their neighborhood …

What is Lrapa air quality PurpleAir?

LRAPA has deployed a network of low-cost air quality Purple Air sensors throughout Lane County. The Purple Air sensors provide particulate matter (PM) data in communities without regulatory monitors.

What AQI is unhealthy?

An AQI over 150 is considered unhealthy for the general population. AQI over 101 can be unhealthy for sensitive groups and some workers with asthma and other conditions may feel unhealthy when the AQI is below 150.

What sensors does PurpleAir use?

PurpleAir uses PMS5003 and PMS1003 laser particle counters. These sensors count suspended particles in sizes of 0.3, 0.5, 1.0, 2.5, 5.0, and 10um. These particle counts are processed by the sensor using a complex algorithm to calculate the PM1.

How long do PurpleAir sensors last?

The sensor is yours to keep! We ask that the sensor be installed for at least two years but we would appreciate it if you could keep the sensor plugged in for as long as possible.

Is there an app for PurpleAir?

Although PurpleAir currently does not have an app, there is a free iOS app called Local Haze which supports PurpleAir’s monitors. The app detects the nearest sensor to you and displays some basic data for the PM2. 5 concentration in real-time.

Why is PurpleAir different than AirNow?

Why does the AirNow Fire and Smoke Map look different than the PurpleAir Map? … AirNow identifies potentially malfunctioning sensors based on a comparison of readings from the two fine particle sensors each PurpleAIr sensor contains, or from user reports.

What are PM2 5?

Fine particulate matter (PM_2.5) is an air pollutant that is a concern for people’s health when levels in air are high. PM_2.5 are tiny particles in the air that reduce visibility and cause the air to appear hazy when levels are elevated.

How does PurpleAir measure air quality?

PurpleAir sensors use a laser particle counter to count the number of airborne particles in the air. That count is used to calculate a mass concentration, assuming an average particle density in an algorithm developed by the laser counter manufacturer, Plantower.

What is the best site for air quality?

There are a lot of websites that offer a similar set of features without installing anything. Two you should try are BreezoMeter and Aqicn. Both of them provide largely accurate results. As it turns out, Aqicn actually stems from a social enterprise project called The World Air Quality Index Project.
