Date: March 13, 2008 To: Chris Vincent From: Matthew Swaters Subject: Calibration of a solid state tilt sensor. Summary In the experiment we used a Microelectromechanical System (MEMS) tilt sensor that couples mechanical elements with electrical elements to detect a DC response with respect to the sensors inclination relative to gravity. The output voltage from the CXTA01 analog sensor is a function of the voltage at 0 inclinations and the magnitude of gravity parallel to the sensor and can be modeled by Eq 1. Equation where v is the sensor voltage output, vo is the zero angle voltage and a is the sensitivity In addition to the analog sensor we also looked at the CXTILT02E digital sensor that relays information to a computer through a standard serial port and can display the output voltage directly on the computer screen. Procedure The CXTA01 sensor is supplied 8 volts DC source and the measurement is taken -60 from below and repeated at 10 intervals increasing to 60 degrees. The measurements are
