SOUND DETECTOR MODULE (SMALL)

A microphone module with a small electret capsule. Output ‘DO’ (active
nhigh) is switched when the sound level exceeds a preset level. A pot allows
nadjustment of the level. The analog output signal is available at the ‘AO’
npin. Except for the smaller size of the capsule and its lower sensitivity the
nmodule is identical to the ‘Big Sound’ module.
