Description

  • Basic noise instrument that measures the sound level of the surrounding environment
  • Simple Conversion: linear analog output
  • Linear correspondence: 30~130dBA, no complex algorithm is required
  • Supports a wide input voltage of 3.3~5.0V and a voltage output of 0.6~2.6V
  • Can be applied to environmental noise testing, such as highway noise monitoring station, etc.
  • Compatible with Arduino Uno R3 USB Microcontroller

The Gravity Analog Sound Level Meter (also known as the decibel meter, noise meter) is a basic noise measurement instrument. This sound level meter is compatible with Arduino. It can accurately measure the sound level of the surrounding environment. This product uses an instrument circuit and a low noise microphone. It supports a wide input voltage of 3.3~5.0V and a voltage output of 0.6~2.6V.

The decibel value is linear with the output voltage, which leads to a simple conversion, without complex algorithm. Sound level meter is widely used in environmental noise detection, such as highway noise monitoring station, room noise monitoring and so on.
