Product Description
Description:
The Grove - Loudness Sensor is designed to detect the loudness of environmental sound. Based on the LM2904 amplifier and with 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 filtering twice inside the module. Lastly, there is a screw potentiometer that enables manual adjustments to the output gain.
Features:
