Gravity Analog Sound Level Meter

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.
