Accelerometer, gyroscope, magnetic sensor, barometer, illuminance sensor, proximity sensor—dozens of MEMS chips are silently working in your pocket at this very moment.

SENSORIUM 98 is a sensor viewer that allows you to view and observe these sensors as if they were "museum collections."

With a retro instrument panel reminiscent of the measuring instrument utilities found on 90s computers, it's like a "smartphone sensor encyclopedia," where each sensor is tagged (vendor, model number, specifications) and enshrined.

────────────────────
■ Zero permissions. Zero communication. That's the proof.

────────────────────

This app does not request any Android permissions.

It doesn't even have INTERNET permission, so by its very nature, it cannot send any data externally.

* Zero Permissions: No uses-permission declaration
* Zero Communication: No INTERNET permission = Structurally offline
* ​​Zero Ads: No ad SDKs, analytics SDKs, or anything else
* Zero Background Use: Completely stops when the app is closed. No background consumption.

Proving "not suspicious" not with words, but with structure. That's the design philosophy of SENSORIUM 98.

────────────────────
■ Include all available sensors.

────────────────────
Including standard sensors, vendor-specific sensors dependent on the device, and even older sensors that are now deprecated, everything the device returns is stored in the encyclopedia.

* List all installed sensors (with vendor name, model number, power consumption, resolution, and maximum range)
* Standard sensors that are not installed are also recorded in the encyclopedia with a "Not installed on this model" plate.
* Display the count of installed/known types. The encyclopedia changes every time you change devices.

You can find out "What kind of IMU does this device have?" with a single tap.
────────────────────
■ All instruments are custom-made for this app.

────────────────────

We don't use off-the-shelf graph libraries. Waveform oscilloscope, wireframe cube showing rotation, barometer, illuminance bar, proximity sonar—all instruments are custom-designed and drawn in-house specifically for this app's aesthetic.

• Real-time waveform display (X/Y/Z 3-axis color)
• Rotation vectors move freely as 3D cubes
• Full-screen display of instruments of interest + raw log + high-speed sampling
• Scanline effect ON/OFF, CRT green/amber color scheme
• And… "Yumekawa Mode" included. With a pastel pink casing and a night sky blue screen, even the sensors want to be Yumekawa.

────────────────────
■ For Developers, Robotics Enthusiasts, and Gadget Lovers
────────────────────
• Tap to copy values, copy by card, copy entire device summary (Plain/JSON/Markdown)
• Unit switching: m/s²⇔g, hPa⇔mmHg, ℃⇔℉
• 5 update rates from ultra-energy-saving to 200Hz. Battery-friendly observation mode also available.
• Pin frequently used sensors to the top.

────────────────────
■ One-time purchase. That's it.

────────────────────
No in-app purchases. No subscriptions. No additional purchases.
Once you buy it, it's all yours.

*The types and number of built-in sensors vary depending on the device. This app is not for "adding" sensors, but rather a visual guide for observing what's on your device.
*The terms of service are unusually short because there is no data to collect. ## Rankings - #3,160,562 — Overall ## Permissions and access ### Permissions - `com.achapoko.sensorium98.DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION` - `com.android.vending.CHECK_LICENSE` ## Similar extensions and apps - [センサー閲覧](https://chrome-stats.com/d/com.harmonic.iot) — 2 users - [Sensor Sense](https://chrome-stats.com/d/com.kristofjannes.sensorsense) — 635,716 users, 3.73 / 5 - [Sensorium](https://chrome-stats.com/d/com.avokiddo.games.google.emoti) - [Sensor Info Lite](https://chrome-stats.com/d/com.tools.sensorinfolite) — 12 users - [내 폰 센서](https://chrome-stats.com/d/com.jooa.smartphone_sensor_1) — 3 users - [Device sensors](https://chrome-stats.com/d/ar.click.allsensors) — 59 users - [PhoneSensor](https://chrome-stats.com/d/com.my.phonesensor) — 56 users - [Sensor Lab: Sensor Test Tools](https://chrome-stats.com/d/com.random.sensor) — 15 users - [SensorLab: Sensor Data Logger](https://chrome-stats.com/d/com.darahat.sensorlab) — 278 users - [Sensor](https://chrome-stats.com/d/com.graytsar.sensor) — 15,281 users, 4.57 / 5 - [Remote Sensor](https://chrome-stats.com/d/com.humanfirstech.remotesensor) — 1,087 users - [SensorLab](https://chrome-stats.com/d/com.fabricionarcizo.sensorlab) — 41 users --- Source: [Chrome-Stats](https://chrome-stats.com/d/com.achapoko.sensorium98)
