Looking for Waveshare Sound Sensor? Waveshare Sound Sensor is available at Zbotic with fast shipping across India.
LM386 is an audio power amplifier with features of low power consumption, adjustable voltage gain, wide voltage power supply, fewer requirements on peripheral components, and minimum total harmonic distortion. LM386 can be applied to consumer products with low voltage requirements. To minimize the number of peripheral components used, the voltage gain should be set to 20.
In the case of working with an MCU:
VCC ↔ 3.3V ~ 5.3V
GND ↔ power supply ground
AOUT ↔ MCU.IO (analog output)
DOUT ↔ MCU.IO (digital output)
Applications:
- Audio amplifier
- Ambient sound detection
- Sound level detection
Features:
- Onboard audio power amplifier LM386
- Audio signal gain up to 200
- Adjustable accuracy
- Signal output indicator
Package Includes:
1 x Sound Sensor
1 x 4-pin custom connector jumper wire

How to Use Waveshare Sound Sensor
Connect VCC to a 3.3 V–5.3 V supply and GND to the common ground. Feed AOUT into your microcontroller’s ADC pin to read the audio waveform and use DOUT on a GPIO pin to detect when sound amplitude passes a built-in threshold. Secure the module using standard M2 screws in its mounting holes and adjust your code to interpret sound levels or trigger events.
