This Grove Loudness Sensor is designed with an amplifier LM2904 and a built-in microphone for accurate sound detection. It features signal conditioning and gain control for precise measurements. The sensor utilizes an electret mic and a two-stage high-pass filter with an LM2904 OP-AMP to create a detectable envelope signal for your projects.
The sensor amplifies and filters the high-frequency signal from the microphone, providing a positive envelope output based on the sound input level. With double filtering inside the module, signal disturbances are minimized. Additionally, the built-in screw potentiometer allows manual adjustments to the output gain.
