Minuscule MEMS Microphone

for the Bat DetectorPLUS

Minuscule MEMS Microphone
To be able to listen to bats you need to have a special detector that translates the high frequency signals (20 to 100 kHz) to sounds that are audible to humans. Elektor’s recent ‘Bat DetectorPLUS ‘ uses a special microphone that is suitable for these high frequencies. But the device package is so small and difficult to solder that this requires a considerable amount of care.
