About this app

Advanced Sensor Monitor turns your phone into a pocket lab: see every sensor live, use it as a compass or a bubble level, follow your route on the map and export the data to CSV.

Tools
• Compass with heading, pitch and roll
• Bubble level: lay the phone flat or stand it on an edge; it turns green when it's level
• Map with your position, its accuracy and your route
• Live charts with min, max and average for every sensor
• Record the data to CSV, ready for Excel, Python, MATLAB or R
• Sampling interval from 100 ms
• Keep the screen on during long measurements

Sensors (depending on your phone)
• Accelerometer, linear acceleration, gravity and G-force
• Gyroscope
• Magnetometer (magnetic field)
• Barometer (atmospheric pressure)
• Light (lux)
• Proximity
• Ambient temperature and relative humidity
• Battery: temperature, voltage and level
• GPS: latitude, longitude, elevation and speed

If your phone is missing a sensor, the app tells you which ones are not available.

Great for
• Science experiments and classroom demos
• Checking that your phone's sensors work
• Hanging a picture straight or levelling a shelf
• Electronics, IoT and robotics projects
• Sports and motion tracking
• Weather and environment logging

A clean, dark design with a card for each sensor, in many languages.

Nice app. Is there a way for it to keep logging while running on the background? I start logging, but logging stops as soon as I switch to a different app. I would give it five stars if it weren't for this logging annoyance.

Nice app, but rotation vector is missing. Also, sampling rate is only up to about 60 Hz

Installed because of the screen shot showing temperature. No temperature settings or reading. Uninstalling.

The app access the ambient temperature sensor, but only if the device has one. Obviously, it cannot read data from a non-existent sensor. Best regards, Bicasoft Support
