Sensor Lab: Sensor Test Tools

Sensor Lab is an all-in-one sensor test toolbox that turns your phone's built-in sensors
and hardware into simple, honest tools. No clutter and no fake readings — just clear,
live data you can actually use, plus a multi-sensor data logger for when you want to
record it.

Whether you're a student, maker, DIY tinkerer, or just curious what your phone can
measure, Sensor Lab puts 15 tools in one clean app.

🧭 MOTION & POSITION
• Compass — find magnetic north
• Bubble level — check if a surface is flat
• Accelerometer, gyroscope & magnetometer live readouts
• Gyro spin meter

📏 METERS
• Sound level meter (decibel-style mic meter)
• Audio spectrum analyzer
• Light meter (lux)
• Proximity sensor tester
• Metal detector — magnetic-field detector

📷 CAMERA TOOLS
• QR code & barcode scanner
• Heart-rate check using the camera (just for fun)

🛠️ SYSTEM & UTILITIES
• Flashlight with strobe & SOS
• Vibration tester
• Device info & full sensor dashboard — see every sensor your phone has

📊 SENSOR LOGGER
The standout feature: record multiple sensors at once to CSV. Choose your sources and
sample rate, watch a live chart while it runs, then open, rename, share or export your
logs. Perfect for science projects, experiments and motion analysis.

🔒 YOUR DATA STAYS YOURS
Sensor readings and recordings are processed on your device and saved only inside the
app — we never upload them. Ads use a standard Google advertising ID; that is the only
data that leaves your phone.

✅ HONEST BY DESIGN
Readings depend on your specific phone's hardware and are meant for everyday,
educational use — not certified measurement. The heart-rate tool is for fun and is NOT a
medical device. The metal detector senses changes in the magnetic field around your phone.

Free to use with ads. A one-time "Remove ads" purchase unlocks an ad-free experience —
no subscription.
