YAHBOOM® 3pin Voice Sound Detection Sensor Module Intelligent Smart Vehicle Robot Helicopter Airplane Aeroplane Car for

Description The sound sensor is suitable for use in all MCU development boards development kits and smart cars Through the simple processing of the signal by the single chip microcomputer interesting experiments such as music fountain and voice control car can be realized The sensor module only occupies one IO port and the volume is judged by the signal length vibration time Only the vibration time can be measured so the timbre and audio cannot be judged An detect the intensity of the sound environment use note the sound sensor can identify the presence of according to the principle of vibration or a particular frequency of sound does not recognize the volume of the soundSensitivity adjustable digital potentiometer to adjust blue Working voltage 3 3 V 5 V Output form digital switch output 1 s and 0 s v Has a fixed bolt hole convenient installationSmall board PCB size 3 2 cm 1 7 cmModule wiring instructions VCC voltage is 3 3 V to 5 V converter which can be directly connected to 5 V single chip microcontroller and 3 3 V GND external GNDOUT of small plate switch output interface 0 and 1 Feature 1 Sound module sound intensity is the most sensitive to the environment commonly used to detect the intensity of the sound of the surroundings 2 Module in the intensity of the sound environment than set threshold the OUT output high level when the intensity of the sound from the outside environment more than set threshold the module OUT output low level 3 S
