Custom datalogger housing design. A Exploded view of logger housing demonstrates each component of the encapsulation. B Inset shows the custom-printed circuit board (PCB), which holds the logger and routes electrophysiological signals to connectors on its underside. Top (C) and side (D) views of the logger show the position of the logger when mounted on the custom PCB. E Detailed view of housing cap showing retaining systems for illumination and pressure sensors
