<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="pi">-</span> <span class="s">humidity</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 (<em>Required</em>): Conditions to monitor. Available conditions are only <em>temperature</em> and <em>humidity</em>.</li>
|
||
<li><strong>temperature_offset</strong> (<em>Optional</em>): Add or subtract a value from the temperature.</li>
|
||
<li><strong>humidity_offset</strong> (<em>Optional</em>): Add or subtract a value from the humidity.</li>
|
||
</ul>
|
||
<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>
