|
<ul>
|
|
<li>sensors -u - Show raw sensor data</li>
|
|
</ul>
|
|
<ul>
|
|
<li>sensors -A - Show adapter information</li>
|
|
</ul>
|
|
<ul>
|
|
<li>sensors -j - Output in JSON format</li>
|
|
</ul>
|
|
<ul>
|
|
<li>sensors -f - Output in Fahrenheit</li>
|
|
</ul>
|
|
<ul>
|
|
<li>sensors -c <config> - Use specific config file</li>
|
|
</ul>
|
|
<hr>
|
|
<h2>Sensor Detection</h2>
|
|
<ul>
|
|
<li>sensors-detect - Detect and configure sensors</li>
|
|
</ul>
|
|
<ul>
|
|
<li>sensors-detect --auto - Auto-detect without prompts</li>
|
|
</ul>
|
|
<ul>
|
|
<li>sensors-detect --batch - Batch mode (no prompts)</li>
|
|
</ul>
|
|
<hr>
|
|
<h2>Configuration</h2>
|
|
<ul>
|
|
<li>sensors -s - Set sensor limits from config</li>
|
|
</ul>
|
|
<ul>
|
|
<li>sensors -c <file> - Use custom config file</li>
|
|
</ul>
|
|
<ul>
|
|
<li>sensors --set-adapter <adapter> - Set adapter</li>
|
|
</ul>
|
|
<hr>
|
|
<h2>Output Options</h2>
|
|
<ul>
|
|
<li>sensors -u - Raw/unformatted output</li>
|
|
</ul>
|
|
<ul>
|
|
<li>sensors -A - Show adapter names</li>
|
|
</ul>
|
|
<ul>
|
|
<li>sensors -j - JSON output</li>
|
|
</ul>
|
|
<ul>
|
|
<li>sensors -f - Fahrenheit instead of Celsius</li>
|
|
</ul>
|
|
<ul>
|
|
<li>sensors -h - Show help</li>
|
|
</ul>
|
|
<hr>
|
|
<h2>Common Examples</h2>
|
|
<h3>Basic Reading</h3>
|
|
<pre><code>sensors</code></pre>
|
|
<p>Display all sensor readings.</p>
|
|
<h3>Raw Data</h3>
|
|
<pre><code>sensors -u</code></pre>
|
|
<p>Show raw sensor data with chip names.</p>
|
|
<h3>JSON Output</h3>
|
|
<pre><code>sensors -j</code></pre>
|
|
<p>Output in JSON format for scripting.</p>
|
|
<h3>Fahrenheit</h3>
|
|
<pre><code>sensors -f</code></pre>
|
|
<p>Display temperatures in Fahrenheit.</p>
|
|
<h3>Detect Sensors</h3>
|
|
<pre><code>sudo sensors-detect</code></pre>
|
|
<p>Detect and configure hardware sensors.</p>
|
|
<h3>Auto Detect</h3>
|
|
<pre><code>sudo sensors-detect --auto</code></pre>
|
|
<p>Auto-detect sensors without prompts.</p>
|
|
<h3>Real-time Monitoring</h3>
|
|
<pre><code>watch -n 1 sensors</code></pre>
|
|
<p>Monitor temperatures in real-time, updating every second.</p>
|
|

|
<h2>Tips</h2>
|
|
<ul>
|
|
<li>Run sensors-detect first to detect hardware sensors</li>
|
|
</ul>
|
|
<ul>
|
|
<li>Use -j for JSON output when scripting</li>
|
|
</ul>
|
|
<ul>
|
|
<li>Use -u to see raw chip data and sensor names</li>
|
|
</ul>
|
|
<ul>
|
|
<li>Use -f if you prefer Fahrenheit temperatures</li>
|
|
</ul>
|
|
<ul>
|
|
<li>Combine with watch for real-time monitoring: watch -n 1 sensors</li>
|
|
</ul>
|
|
<ul>
|
|
<li>Use sensors -s to apply limits from configuration</li>
|
|
</ul>
|
|
<ul>
|
|
<li>Check /etc/sensors3.conf for configuration options</li>
|
|
</ul>
|
|
<ul>
|
|
<li>Essential for monitoring CPU and system temperatures</li>
|
|
</ul>
|
|
<ul>
|
|
<li>Use watch sensors to monitor temperatures in real-time (updates every 2 seconds by default)</li>
|
|
</ul>
|
|
<ul>
|
|
<li>For custom update interval: watch -n 0.5 sensors (updates every 0.5 seconds)</li>
|
|
</ul>
