Dual sound sensor on the basis of LM386 and LM393

The submission represent experimental module double sonic sensor on the basis of two audio amplifiers and double LM386 comparator LM393

The scheme is quite simple sound sensor and is a standard inclusion of elements. Audio Amplifiers LM386 included on the scheme maximize signal (datashit cm) LM393 Heightened elektretnyh signal from the microphone comes on two channels comparator LM393.

R5 resistor construction allows it to adjust the threshold comparator operation - sensitivity. Thus at the exit scheme, we get two logical signal - from right and left of microphones. Also, there is an opportunity to process an analog signal directly from the amplifier through the ADC. J1. Options outgoing signals switched through two jumpers in the shoe J1.
