Design and realization of ADXL203 posture detection platform based on LabVIEW

The ADXL203 is high precision, low power and dual axis accelerometers which is produced by ANALOG DEVICES. In this paper, the author puts forward a way to construct the ADXL203 posture detection platform. Firstly, the application platform framework is devised, using PC, NI USB-6259 and acceleration sensor to build the ADXL203 posture detection hardware platform. Then the system software is developed based on LabVIEW virtual instrumentation development environment. Finally, taking HMR3000 as the standard components to calibrate the output voltage of ADXL203 in order to improve the accuracy of the posture angle measurment.
