<hr class="divider">
<p>The <code class="highlighter-rouge">airvisual</code> sensor platform queries the <a href="https://airvisual.com/">AirVisual</a> API for air quality
data on the nearest city to a latitude and longitude. The resulting information
creates sensors for the Air Quality Index (AQI), the human-friendly air quality
level, and the main pollutant of that area. Sensors that conform to either/both
the <a href="http://www.clm.com/publication.cfm?ID=366">U.S. and Chinese air quality standards</a> can be created.</p>
<p>This platform requires an AirVisual API key, which can be obtained <a href="https://airvisual.com/api">here</a>. Note
that the platform was designed using the “Community” package; the “Startup”
and “Enterprise” package keys should continue to function, but actual results
may vary (or not work at all).</p>
<p class="note warning">
The “Community” API key is limited to 10,000 calls per month. In order to leave
a buffer, the <code class="highlighter-rouge">airvisual</code> platform queries the API every 10 minutes.
</p>
<h2><a class="title-link" name="configuring-the-platform" href="#configuring-the-platform"></a> Configuring the Platform</h2>
<p>To enable this platform, add the following lines to your <code class="highlighter-rouge">configuration.yaml</code>
file:</p>
<div class="language-yaml highlighter-rouge"><pre class="highlight"><code><span class="s">sensor</span><span class="pi">:</span>
<span class="pi">-</span> <span class="s">platform</span><span class="pi">:</span> <span class="s">airvisual</span>

</div>
<p>Configuration variables:</p>
<ul>
<li><strong>api_key</strong> (<em>Required</em>): your AirVisual API key</li>
<li><strong>monitored_conditions</strong> (<em>Required</em>): the air quality standard(s) to use
(<code class="highlighter-rouge">us</code> for U.S., <code class="highlighter-rouge">cn</code> for Chinese)</li>
<li><strong>latitude</strong> (<em>Optional</em>): the latitude to monitor; if excluded, the latitude
defined in <code class="highlighter-rouge">configuration.yaml</code> will be used</li>
<li><strong>longitude</strong> (<em>Optional</em>): the longitude to monitor; if excluded, the longitude
defined in <code class="highlighter-rouge">configuration.yaml</code> will be used</li>
<li><strong>radius</strong> (<em>Optional</em>): the radius (in meters) around the latitude/longitude to
search for the nearest city; defaults to <code class="highlighter-rouge">1000</code></li>
</ul>
<h2><a class="title-link" name="sensor-types" href="#sensor-types"></a> Sensor Types</h2>
<p>When configured, the platform will create three sensors for each configured
air quality standard:</p>
<h3>Air Quality Index</h3>
<p><strong>Description:</strong> This sensor displays a numeric air quality index (AQI), a metric
for the overall “health” of the air.</p>
<p><strong>Example Sensor Name:</strong> <code class="highlighter-rouge">sensor.chinese_air_quality_index</code></p>
<p><strong>Example Sensor Value:</strong> <code class="highlighter-rouge">32</code></p>
