Retrieve AQI (with AQandU conversion) from a PurpleAir sensor via the CLI or as a library to your node script
Most of this code was stolen from https://aqi.wtf
Open the PurpleAir map: https://www.purpleair.com/map?mylocation
and click on the sensor closest to your location.
The URL bar will change to something like:
https://www.purpleair.com/map?opt=1/mAQI/a10/cC0&select=62217#15.69/37.737125/-122.414218
The sensor ID will be the value of the select parameter. In the above URL, the ID is 62217:
https://www.purpleair.com/map?opt=1/mAQI/a10/cC0&select=62217#15.69/37.737125/-122.414218
Install the module globally
npm install -g purpleair
Then call:
purpleair [sensor ID]
which will return the AQI.
Example output:
>
64B3
purpleair 62217
139
With the AQI class:
> purpleair --class 62217
139 (unhealthy-for-sensitive-groups)
As JSON:
> purpleair --class --json 62217
{
"aqi": 139,
"sensorId": 62217,
"class": "unhealthy-for-sensitive-groups"
}
There are three functions:
- getSensor(sensorId)
- getAQI(sensor)
- getAQIClass(aqi)
Example:
const purpleair = require('purpleair');
const main = async () => {
try {
var sensor = await purpleair.getSensor(62217);
var aqi = await purpleair.getAQI(sensor);
console.log(aqi);
var aqiClass = purpleair.getAQIClass(aqi);
console.log(aqiClass);
} catch (err) {
console.error(err);
}
};
main();
