SensorPulse – User Manual

1. Introduction – What is SensorPulse?

SensorPulse is a complete hardware monitoring suite for Windows 10 and 11. It reads sensor data from your PC – CPU temperature, GPU load, fan speed, disk usage, network adapters and more – and displays everything in clear tiles, charts and tables.

What SensorPulse can do

• Live dashboard with colored tiles, sparklines, favourites bar at top and hardware grouping
• History charts with zoom and detailed reading explanations
• Custom alarm thresholds, alert sidebar and alert history
• Tools Hub with fan control, GPU info, benchmark, export and more
• Built-in Task Manager with process actions and performance charts
• Transparent game overlay for CPU/GPU/FPS while gaming
• Program launcher for installed apps and games
• SQL Admin and automation (full license, protected against manipulation)

Privacy – everything local, no cloud

SensorPulse runs entirely on your PC. There are no user accounts, no cloud sync and no telemetry to external servers. Readings are stored in a local SQLite database (sensordata.db) next to the application – only when you enable it in settings.

7-day trial

After the first start you automatically get a free 7-day trial. During this period you can use full monitoring, history, overlay, export, benchmark, per-sensor pause, tools and Task Manager. Premium features (SQL admin, automation, auto fan curves, large-file scanner, group pause) require the full license.

When the trial ends, live monitoring stops. Unlock SensorPulse anytime with a one-time PayPal payment of €4.99 (see chapter 12).

2. Installation

SensorPulse is available in three variants. Choose the right method on the download page.

Option A: Online Setup (recommended)

1. Open sensorpulse.de/download.html in your browser.
2. Click “Download online setup”. The file is named SensorPulse.Setup.exe (language matches the website).
3. Double-click the setup file. Windows may ask for confirmation – click Yes.
4. The wizard starts and downloads the application package from the internet. Make sure you are online.
5. Choose the destination folder (default is fine).
6. Enable or disable desktop shortcut and Start menu entry as you prefer.
7. Click Install and wait until “Finished” appears.
8. Launch SensorPulse from the shortcut or Start menu.

Option B: Offline Setup

1. Download the offline bundle (ZIP) from the download page.
2. Extract the ZIP to a folder of your choice.
3. Run the included SensorPulse.Setup.Offline.exe.
4. Follow the wizard like the online install. No internet is needed – everything is in the package.
5. Finish installation and start SensorPulse.

System requirements

• Windows 10 or 11, 64-bit
• .NET Framework 4.8 (usually pre-installed)
• About 50 MB free disk space
• WebView2 runtime included in the package (runtimes\ folder)

3. First Launch

On the very first start SensorPulse runs through several steps. This can take 10–30 seconds – please wait until the dashboard appears.

Step by step on first launch

1. Start SensorPulse.exe with a double-click.
2. A loading screen appears with progress: database, settings, license, hardware sensors.
3. After loading you see a short 7-day trial notice (e.g. “Your 7-day evaluation is active – X days remaining”). It disappears automatically.
4. The main window opens on the Sensors tab with the first sensor tiles.
5. Monitoring usually starts automatically. Values refresh every few seconds.

Understanding the trial

Trial status is shown in the status bar and under the License button. You can activate anytime – remaining trial days are displayed. After 7 days an overlay appears; monitoring pauses until you enter a license.

Administrator rights

If few or no temperature sensors appear:

1. Click Settings (gear icon) in the status bar.
2. Click Run as administrator.
3. Confirm the Windows UAC prompt with Yes.
4. SensorPulse restarts with elevated rights. More sensors should now be visible.

PawnIO (optional, for AMD CPU sensors)

Direct CPU temperature reads on some AMD processors need the PawnIO driver. If SensorPulse reports this:

1. Start SensorPulse as administrator (see above).
2. The PawnIO installer may run automatically if bundled.
3. Alternatively download PawnIO from pawnio.eu and install manually.
4. Restart SensorPulse as administrator afterwards.

4. Main Dashboard

The dashboard is your central screen. Here you see all live sensor values at a glance.

Sensors tab

1. Make sure the Sensors tab is active (next to Programs).
2. The sensor list is grouped by hardware: CPU, GPU, motherboard, memory, storage, network, battery, etc.
3. Groups are stacked vertically; tiles within a group are arranged side by side.
4. Each group can be expanded or collapsed by clicking the group name.

Summary cards

At the top you see four cards: SENSORS, NORMAL, WARNING, CRITICAL.

1. Click SENSORS to show all sensors (clear filter).
2. Click NORMAL to show only green, OK sensors.
3. Click WARNING to filter yellow sensors only.
4. Click CRITICAL to show only red sensors.
5. Click the same card again to clear the filter.

Search

1. Click the search box “Filter sensors by name, hardware or type…” or press Ctrl+F.
2. Type a term, e.g. “CPU” or “Temperature”.
3. Only matching sensors are shown. Press Esc to clear the search.

Favorites

1. Right-click a sensor tile.
2. Choose Add to favorites.
3. The sensor appears in the Favorites group at the top of the list – highlighted and independent of hardware grouping.
4. To remove: right-click → Remove from favorites.

Groups and sparklines
