sound detection module whistle voice-activated switching outputs high and low level DIY
 
 Product features:    

1 can detect ambient sound intensity, usage note: this sound sensor can only identify the presence or absence of (based on the principle of vibration) does not recognize the voice or sound with a specific frequency    
2 adjustable sensitivity (shown in blue digital potentiometer adjustment)    
3 operating voltage 3.3V-5V    
4 output digital switching outputs (high and low level 0 and 1)    
5 fixed bolt holes for easy installation    
6 small Board PCB dimension: 3.2cm * 1.7cm    
 
Module wiring instructions    

1 an external 3.3V-5V voltages VCC (5V directly connected to a single-chip computer 3.3V single-chip)    
2 GND external GND    
3 OUT small-plate digital output interfaces (0 and 10
 
Instructions for use    

1 sound module sound intensity is the most sensitive to the environment, generally used for detecting ambient sound intensity.    
2 module on the environmental sound strength less than the set threshold value, the OUT output level when the outside ambient sound intensity exceeds the set threshold value, the modules OUT output low level;    
3 small-plate digital output OUT can be directly connected to the microcontroller, by single-chip computer to detect high or low level, thus to detect sound environment;    
4 small-plate digital output OUT can directly drive our relay module, which can be rearranged into a voice-activated switch;
