<p>The <code class="highlighter-rouge">dht</code> sensor platform allows you to get the current temperature and humidity from a DHT11, DHT22, or AM2302 device.</p>
<p>To use your DHTxx sensor in your installation, add the following to your <code class="highlighter-rouge">configuration.yaml</code> file:</p>
<div class="language-yaml highlighter-rouge"><pre class="highlight"><code><span class="c1"># Example configuration.yaml entry</span>
<span class="s">sensor</span><span class="pi">:</span>
<span class="s">platform</span><span class="pi">:</span> <span class="s">dht</span>
<span class="s">sensor</span><span class="pi">:</span> <span class="s">DHT22</span>
<span class="s">pin</span><span class="pi">:</span> <span class="s">23</span>

</code></pre>
</div>
<p>Configuration variables:</p>
<ul>
<li><strong>sensor</strong> (<em>Required</em>): The sensor type, supported devices are DHT11, DHT22, and AM2302</li>
<li><strong>pin</strong> (<em>Required</em>): The pin the sensor is connected to.</li>
<li><strong>name</strong> (<em>Optional</em>): The name of the sensor</li>
<li><strong>monitored_conditions</strong> array: Conditions to monitor.
<ul>
<li><strong>temperature</strong>:</li>
<li><strong>humidity</strong>:</li>
</ul>
</li>
</ul>
<p>Available conditions are only <em>temperature</em> and <em>humidity</em>.</p>
<p>The name of the pin to which the sensor is connected has different names on different platforms. ‘P8_11’ for Beaglebone, ‘23’ for Raspberry Pi.</p>
<p class="note warning">
As this requires access to the GPIO, you will need to run Home Assistant as root.
