Grove - Sound Sensor/ Noise Detector for Arduino
Grove compatible interface Wide supply voltage range Built-in signal filtering
- 10+: $4.50
PRODUCT DETAILS
The 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 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.

What is Grove?
Grove makes it easier to connect, experiment, and simplify the prototyping process. No jumpers or soldering required. We have developed more than 300 Grove modules, covering a wide range of applications that can fulfil a variety of needs. Not only are these open hardware, but we also have open-source software.
Note
For all Grove users (especially beginners), we provide you with the guidance of operation. Please read the instructions through the official website before you using the product.
