About this app

Smart Meter Pro is the NEW 4th set of Smart Tools® collection. It includes 3 tools (Sound meter, Vibration meter and Lux meter).

① Sound meter
Sound level meter uses your microphone to measure noise volume in decibels(db), and shows a reference.

REMEMBER!! Most microphones were aligned to human voice (300-3400 Hz, 40-60 dB). Therefore maximum value is LIMITED by manufacturers, and very loud sound (90+ dB) cannot be recognized.
You can trust the result in routine-noise levels (40-70 dB).

② Vibration meter (seismograph)
Vibrometer uses the acceleration sensors to measure vibration or an earthquake, and it shows a reference as a seismic detector.

The measured values are related to Modified Mercalli Intensity scale (MMI). If it is inaccurate, you can calibrate it so that maximum value is about 10-11. Please use it as an auxiliary tool.

③ Lux meter
Light meter measures the ambient brightness with embedded light sensor. It is used to adjust the lighting required for plants or to check the brightness of a study room.

Make sure that your screen with the sensor is facing the ambient light source (lamp, LED lighting, window, sun).

Ratings and reviews

Very straight forward to use and does not make it overly complex. I used it recently when comparing keyboard switches to decide which switch to buy. Quite easy to use, I can start the audio monitor and then type and stop it to review the measurements. The Pro version also has a color background change option to make it easier to tell once the audio passes a certain threshold which is also convenient, I used it in my noisy office to review.

Exactly what I needed. As a long-haul otr truck driver, I always found myself wondering what kind of vibrations and impacts certain areas of my truck and objects attached within were experiencing out there on very rough roads... most notable would be my desktop computer. Not exactly an ideal environment for a desktop computer but it's best I can do until I find a laptop that equals the desktops capabilities.

The app is great, but it is does not allow you to export the CSV file of a saved recording. It only exports whatever is currently recording. Please fix this, and then the app is perfect.
