Introduction

This is an Arduino compatible sound level meter(also known as decibel meter, noise meter). It uses instrument circuit, low noise microphone, which make it accurately measure the sound level of the surrounding environment. It can be applied to environmental noise testing, such as highway noise monitoring station, bedroom noise monitoring.

In our environment, there are all kinds of sounds, some of which are noise. With the development of human civilization, the quiet environments are less and less, but more and more noisy environments instead. Staying in the noise for long time will have an impact on hearing, which is bad for health.


Arduino DIY Decibel Meter

Sound level meter (also known as the decibel meter, noise meter) is a basic noise measurement instrument. We have launched a sound level meter, which is compatible with Arduino, plug-and-play. It can accurately measure the sound level of the surrounding environment. This product uses instrument circuit, low noise microphone, which make it highly precious. It supports 3.3~5.0V wide input voltage, 0.6~2.6V voltage output. The decibel value is linear with the output voltage, which leads to a simple conversion, without complex algorithm. The connector is plug-and-play, without welding, so this product can be easily used in your application.

Arduino Decibel Meter Wiring

Sound level meter is widely used in environmental noise detection, such as highway noise monitoring station, room noise monitoring and so on. It’s time for you to DIY a sound level detector to protect your hearing.

Attention:
The black film on the microphone is a sensitive component, do not touch it with fingernails or other sharp objects.
Do not place this module on the surface of the conductor or the semiconductor, otherwise it will short the microphone’s pins. It is recommended to place this module on a dry insulator’s surface or fix with nylon columns to hang in the air.
