Sound Sensor Module Volume Recognition Detection for Microbit

Introduction of Sound module1 Working principleThe sound sensor like a microphone It is used to receive sound waves and display a vibrating image of the sound but it cannot measure the intensity of the sound The output analog value of the sound sensor ranges from 0 to 1023 The larger the sound it will output larger analog value of the 2 Practical application2 1 Voice control lamp3 About module3 1 Sound module possess 4 Alligator clip port Corresponding to GND VCC NC and SIG SIG pin is the signal output pins of the module 3 2 4 pin female socket 3 3 PH2 0 cable interface The sound sensor detects the sound of the current environment The louder the volume the larger the output value and the weaker the volume the smaller the output value Working Voltage 3 3V 5V
