Smart Meter Pro

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).
