Multi-sensor CSV logger
Records several sensors at once to a CSV file. Choose the sources and sample rate, watch a live chart while it runs, then rename, share or export the log.
| Sensor used | Any combination the device exposes |
|---|---|
| Unit | CSV — timestamps plus one column set per source |
| Useful range | Sample rate is selectable when you set up a recording |
| Cannot do | Guarantee exact sample timing; Android is not a real-time system |
The mechanism, not the marketing.
You pick which sensors to record and at what rate. Each sample is written with a timestamp, so the resulting CSV can be opened directly in a spreadsheet, Python or R.
A live chart runs while recording, so you can see whether you are capturing what you intended rather than discovering it afterwards. Finished logs can be renamed, shared or exported.
This is the tool that makes the app useful for real work — school science projects, motion experiments, checking vibration on a machine, or capturing a journey's accelerometer trace for later analysis.
What a phone cannot do here.
- Android delivers sensor events on a best-effort basis. A requested rate is a hint, not a contract, so intervals jitter and the actual rate may sit below what you asked for. Use the recorded timestamps rather than assuming a fixed step.
- Higher rates and more simultaneous sensors mean larger files and more battery use.
- The operating system aggressively restricts background work to save power, so long unattended recordings can be interrupted by the system.
Can I export sensor data to CSV?
Yes — that is what the logger produces. Each recording is a CSV with timestamps and a column set per sensor, ready for a spreadsheet or a script.
Can I record several sensors at the same time?
Yes. You select the sources before starting, and they are recorded together against a shared timeline.
Is the sample rate exact?
No. Android treats the requested rate as a hint, so intervals vary. Always use the timestamps in the file rather than assuming even spacing.
Every sensor your phone has, in one app.
