Main Features: 1. High sensitivity sound detection sensor module 2. With a signal output instruction 3. One single channel output; low-level output signal 4. When the sound output is low, lights lit 5. Can be used for voice-activated lights 6. The module has two outputs: AO, analog output, real-time output of the microphone voltage signal; DO, when the sound intensity reaches a threshold, the high and low output signal threshold is adjustable by the potentiometer 7. Applied to single chip microcomputer (SCM) study, Arduino application, sound detection, sound control

Setup Guide

1
Identify the pins
Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.
2
Wire to your microcontroller
Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.
3
Install libraries
In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.
4
Upload example sketch
Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.
5
Calibrate if needed
Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
