MicroMyotis


The µMyotis conditioner (or Micro‑Myotis) is an interface module designed by Phonoptics for use with all their fiber‑optic sensors, such as microphones, Alpheus dynamic pressure sensors, tachometers, and vibration sensors. It integrates a light source, a photodiode, and a microcontroller to provide optoelectronic conversion and signal conditioning.

It is designed for direct integration into a client device or with Phonoptics’ Breakout unit.
