Body Cavity Pressure sensor

This will tell you how to build an anal or vaginal pressure sensor, using an inflatable buttplug or dildo.

What you need

 * An inflatable buttplug or dildo
 * Some plastic tube and glue
 * A 24PCCFA6G pressure sensor
 * An INA122 instrumentation amplifier
 * A 1.5Kohm resistor
 * An Arduino or something else to read the output

Schematics
With only three electrical components the schematics is simple.



How to assemble
Cut a small hole in the side of the tube to the inflatable buttplug, and glue the plastic tube to the hole. Air should be able to flow freely into the tube, and the connection should of course be airtight. Connect the other end of the tube to the pressure sensor, build the circuit, and you are done.
