Sound Sensor available at Tomson Electronics, Kochi, Kerala, India is the best quality product.This is a multipurpose sound sensor which can be used to sense sound and audio. The sensor provides a digital output when the measured sound increases beyond a set threshold. This threshold level can be adjusted using an onboard potentiometer. The sensor outputs a logic one(+5V) at the digital output when it detects sound and a logic zero(0V) when there is no sound detected. An onboard LED is used to indicate the output status. This digital output can be directly connected to an Arduino, Raspberry Pi, AVR, PIC, 8051 or any other microcontroller to read the sensor output.
