For the purpose of inclination measurement and monitoring, a tilt angle measurement system using a heat convection accelerometer is presented in this study. A conditioning circuit that center around the single chip processor is designed and built. Experiments were carried out to characterize the measuring system with the range of-90° to +90°. The output results show nonlinear relationship. The calibration result indicates that the sensitivity of the accelerometer is about 650mV/g. The maximum error is 5.5% while the repeatability error is 3%. Experiments proved that the developed measurement system is capable of measuring tilt angle.

Abstract The DataHawk small airborne measurement system provides in situ atmospheric measurement capabilities for documenting scales as small as 1 m and can access reasonably large volumes in and above the atmospheric boundary layer at low cost. The design of the DataHawk system is described, beginning with the atmospheric measurement requirements, and articulating five key challenges that any practical measurement system must overcome. The resulting characteristics of the airborne and ground support components of the DataHawk system are outlined, along with its deployment, operating, and recovery modes. Typical results are presented to illustrate the types and quality of data provided by the current system, as well as the need for more of these finescale measurements. Particular focus is given to the DataHawk's ability to make very-high-resolution measurements of a variety of atmospheric variables simultaneously, with emphasis given to the measurement of two important finescale turbulence parameters, (the temperature turbulence structure constant) and ɛ (the turbulent energy dissipation rate). Future sensing possibilities and limitations using this approach are also discussed.
