Measurement and use of noise in industrial plants

Abstract

The article presents the original design of the sound level meter with software based on Arduino-mini, which provides sending noise level values in decibels to other devices. After exceeding the noise level above the permissible sanitary standards, information is automatically sent to devices capable of converting sound vibrations into electric current. After the accumulation of such alternative energy with the help of an ionistor, it becomes possible to use it, for example, for night lighting of office buildings and much more.
