he sound sensor module provides an easy way to detect sound and is generally used for detecting sound intensity. This module can be used for security, switch, and monitoring applications. Its accuracy can be easily adjusted for the convenience of usage.Sound Detection Sensor Module for Arduino detects whether sound has exceeded a threshold value. The sound is detected via microphone and fed into an op-amp The sound level setpoint is adjusted via an onboard potentiometer. When the sound level exceeds the set point, an LED on the module is illuminated and the output is sent low It uses a microphone which supplies the input to an amplifier, peak detector and buffer. When the sensor detects a sound, it processes an output signal voltage which is sent to a microcontroller then performs necessary processing. This sensor can be used to build various electronic projects with the help of an Arduino board. which fundamentally gives your Arduino’s ears. A microphone can be attached to an analog pin of the board. This can be used to notice the noise level within the nearby surroundings. This sensor support platforms like Arduino, Raspberry Pi, BeagleBone Wio, and LinkIt ONE. This sensor plays an essential role while activating the light in your office or house by detecting a precise whistle or clap sound The working principle of this sensor is related to human ears. Because human eye includes a diaphragm and the main function of this diaphragm is, it uses the vibrations and changes into signals. Whereas in this sensor, it uses a microphone and the main function of this is, it uses the vibrations and changes into current otherwise voltage Detectable sound signal size Built-in filter-rectifier circuit, dc signal output good sensitivity, built-in amplifier circuit, adjustable gain Voltage signal for sound intensity can be obtained by ad conversion Analog voltage signal output, signal amplitude vcc/2 Package content: robotbanao sound detection sensor module sensor intelligent veh
