3pin Voice Sound Detection Sensor Module Diy Intelligent Smart Vehicle Robot Helicopter Airplane Aeroplane Boart Car – Sensors

• Size:32mm*17mm*8mm(length*width*height)

• Main chip:LM393, Electret condenser microphone

• Working voltage: DC 4-6V

• Signal output indication

• Single channel signal output

• The output effective signal is low level

• When there is sound, outputs low level and the signal light

• Can be used for Acoustic control light , give sound and light alarm working with Photosensitive sensor ,and sound control, sound detect

• Circuit board output switch quantity

• Note: The Maximum induction distance is 0.5

1 can detect the intensity of the sound environment, use note: the sensor can only identify the presence of (according to the principle of vibration) of sound does not recognize the sound or the size of the particular frequency of sound
2 the sensitivity adjustable digital potentiometer to adjust (blue)
3 working voltage of 3.3 V to 5 V
5 output form digital switch output (1 s and 0 s + v)
6 sets of fixed bolt hole, convenient installation
