Gravity: Analog Sound Level Meter Shipping:4-6 Days AC1 Not inductive orThis is an Arduino compatible sound level meter(also known as decibel meter, noise meter). It uses instrument circuit and low noise microphone, which enable it to 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, etc. Nowadays, there are many kinds of sounds surrounding, some of which are really noisy.
