Specification
Brand : cizihuu
BulletPoint1 : Can detect the sound intensity of the surrounding environment, use Note: This sensor can only identify the presence of sound (according to the principle of vibration) can not recognize the size of the sound or a specific frequency of sound
BulletPoint2 : With fixed bolt holes, easy to install
BulletPoint3 : Two module wiring instructions
BulletPoint4 : VCC external 3.3V-5V voltage (can be directly connected with the 5v microcontroller and 3.3v single-chip)
BulletPoint5 : 140 dB, common mode rejection ratio (CMRR) and 36 V common-mode voltage (CMV) within the scope of work to ensure minimal or no changes of offset voltage, which can simplify the error analysis

ProductDescription : Model Number:Sound Detection Sensor
Material:Mixture

Adjustable sensitivity (blue digital potentiometer adjustment)
Operating voltage 3.3V-5V
Output form Digital switch output (0 and 1 high and low level)
Small board PCB size: 3.2cm×1.7cm
OUT small board switch output interface (0 and 1)
Sound module is the most sensitive to the sound intensity of the environment, generally used to detect the sound intensity of the surrounding environment.
When the ambient sound intensity reaches the set threshold, the OUT output high level, when the external ambient sound intensity exceeds the set threshold, the module OUT output low
Small board digital output OUT can be directly connected with the microcontroller, through the microcontroller to detect high and low levels, which to detect the sound of the environment
