Robomart Sound Sensor

The Rm0018 Sound Sensor Provides A Means To Add Noise Control To Your Project And Responds To Loud Noises Such As A Clap Of The Hands. Through The On - Board Microphone, This Sensor Detects Changes In Decibel Level, Which Triggers A High Pulse To Be Sent Through The Signal Pin Of The Sensor. This Change Can Be Read By An I / O Pin Of Any Robmart?S Microcontroller Boards.The Rm0018 Sound Sensor Is A Simple Microphone. Based On The Transistor Amplification And The Electrets Microphone, It Can Be Used To Detect The Sound Strength Of The Environment. The Value Of Output Can Be Adjusted By The Potentiometer.This Module Uses The Npn Transistor Based Amplifier To Strengthen The Electronic Signal Produced By The Electrets Microphone. When Powered On, The Sig Pin Will Output The Signal Regulated By The Transistor. The Potentiometer At The Output Can Be Used To Regulate The Gain.The 555 Timer Ic Provides Mono Stable And Digital Output For Better Usage In Any Processor. The On - Board Potentiometer Provide Gain Value For Timer Ic.
