The Grove-Loudness Sensor is based on amplifier LM2904 and a built-in microphone and is designed to detect the loudness of environmental sound.FeaturesUpgraded functionality: Based on LM2904 －－－ Dual, 36-V, 1.2-MHz operational amplifier with -40°C to 125°C operationWide supply voltage range: In the range of 3.2V~5.2VBuilt-in signal filtering: Input signal will go through two times filtering inside the moduleAdjustable output gain: A screw potentiometer that enables manual adjustments to the output gainGrove unified socket: The product ensures ＂Plug and Play＂ and could be versatile for various applications of GroveDescriptionThe Grove-Loudness Sensor is designed to detect the loudness of environmental sound. Based on amplifier LM2904 and a built-in microphone, it amplifies and filters the high-frequency signal that is received from the microphone and outputs a positive envelope. This will make for Arduino＇s signal acquisition. The output value depends on the level of the sound input. In order to avoid unnecessary signal disturbances, the input signal will go through two times filtering inside the module. Lastly, there is a screw potentiometer that enables manual adjustments to the output gain.
