This bat detector uses a MEMS microphone for its high sensitivity in the ultra-sonic range. The detector produces a sine wave for the speaker which can be re-modulated with the original amplitude. Four low-pass filter cutoff frequencies, four frequency division ratios and more can be set with DIP switches.
