S37 Automatic Sensor Simulator Project

This test set was built to test the System 37 Recorder (DAU). The DAU records uterine activity using an external sensor place on an expectant mom's abdomen. This test set simulates the signal from the sensor and provides solenoids to activate 2 buttons on the front panel. The test set will generate a 6 minute or a 60 minute test  waveform. The test set includes a custom PCB layout with a microcontroller on board. The case is built from Lexan with custom pockets milled in the top plate to accept the DAU under test.  Testing is started by pressing the "Start" button, sn audible alarm sounds when the test is completed.
