Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the ADXL202/ADXL210 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges ...

... MEASURING 360 OF TILT It is possible to measure a full 360 of orientation through grav- ity by using two accelerometers oriented perpendicular to one another (see Figure 15). When one sensor is reading a maxi- mum change in output per degree, the other is at its minimum. 0 ...
