1. Product features:
(1) It can detect the sound intensity of the surrounding environment. Note: This sensor can only identify the presence or absence of sound (according to the principle of vibration) and cannot identify the size of the sound or the sound of a specific frequency
(2) Sensitivity is adjustable (the blue digital potentiometer is adjusted in the picture)
(3) Working voltage 3.3V-5V
(4) Output form Digital switch output (0 and 1 high and low level)
(5) With fixing bolt holes for easy installation
(6) Small board PCB size: 3.2cm * 1.7cm

2. Module wiring instructions
(1) VCC externally connects 3.3V-5V voltage (can be directly connected with 5v microcontroller and 3.3v microcontroller)
(2) GND connects to GND
(3) OUT small board switch output interface (0 and 1)

3. Instructions for use
(1) The sound module is most sensitive to the intensity of ambient sound, and is generally used to detect the sound intensity of the surrounding environment.
(2) When the module’s environmental sound intensity does not reach the set threshold, OUT outputs a high level; when the external environmental sound intensity exceeds the set threshold, the module OUT outputs a low level;
(3) The digital output OUT of the small board can be directly connected with the single-chip microcomputer, and the high and low level can be detected by the single-chip microcomputer, thereby detecting the sound of the environment;
(4) The small board digital output OUT can directly drive the relay module of our shop, which can form a voice-activated switch;
