SensorPulse – User Manual
Complete step-by-step guide for absolute beginners
Version 2.12.0 · Windows 10/11 (64-bit)New in version 2.12.0: task manager performance details and improved overlay frametime graph.
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 (premium – license required)
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.
Free forever – no key required
SensorPulse (consumer) and Hub (up to 10 PCs, SQLite) are free forever from the first start – no trial, no license key. That includes SQL admin on the local SQLite database, automation, fan control, folder treemap, startup catalog, ICMP ping, benchmark and overlay.
SensorPulse Enterprise (€599 one-time, SPEL-ENT-599) is a separate product for businesses: unlimited devices, agent/server/console, SQL Server/Oracle, server tools and Prometheus /metrics. It is not unlocked via PayPal inside the consumer app.
2. Installation
SensorPulse is available in two variants. Choose the right method on the download page.
Option A: Online Setup (recommended)
- Open sensorpulse.de/download.html in your browser.
- Click “Download online setup”. The file is named
SensorPulse.Setup.exe(language matches the website). - Double-click the setup file. Windows may ask for confirmation – click Yes.
- The wizard starts and extracts the embedded application package. No internet is required during installation.
- Choose the destination folder (default is fine).
- Enable or disable desktop shortcut and Start menu entry as you prefer.
- Click Install and wait until “Finished” appears.
- Launch SensorPulse from the shortcut or Start menu.
Option B: Offline Setup
- Download the offline bundle (ZIP) from the download page.
- Extract the ZIP to a folder of your choice.
- Run the included
SensorPulse.Setup.Offline.exe. - Follow the wizard like the online install. No internet is needed – the application package is embedded in the setup EXE.
- 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
- Start
SensorPulse.exewith a double-click. - A loading screen appears with progress: database, settings, license, hardware sensors.
- After loading you see a short welcome notice (e.g. “SensorPulse – free forever”). It disappears automatically.
- The main window opens on the Sensors tab with the first sensor tiles.
- Monitoring usually starts automatically. Values refresh every few seconds.
Understanding the license status
The status bar and License button show that the consumer app is free. You do not need a key. SensorPulse Enterprise is a separate download (SPEL key) for unlimited fleet monitoring.
Administrator rights
If few or no temperature sensors appear:
- Click Settings (gear icon) in the status bar.
- Click Run as administrator.
- Confirm the Windows UAC prompt with Yes.
