About 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
SPL (sound pressure level) meter uses your microphone to measure noise volume in decibels(db), and shows a reference.

REMEMBER!! Most microphones were aligned to human voice (300-3400Hz, 40-60dB). 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 (40-70dB). Please use it as an auxiliary tool.

② Vibration Meter
Vibrometer uses the phone sensors to measure vibration or an earthquake, and it shows a reference as a seism 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.

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).
