Air quality in Howth

PurpleAir have created an air quality monitoring network built on a new generation of "Internet of Things" sensors.

A PurpleAir member in Thormanby Lawns, Howth has an air quality monitor and provides the data to PurpleAir. The live measurements from this station are shown below. These measurements have been converted to use the Environmental Protection Agency's Air Quality Index for Health (AQIH) which is an index number from one to ten that tells you what the air quality currently is and whether or not this might affect your health (see table below measurements for details of what the index numbers mean).


The map below from PurpleAir uses the US Air Quality Index (AQI). It shows the location of the various sensors and their current readings. You can zoom in and out of this map.
