The Phidget GPS provides the longitude and latitude of the board's position in signed decimal degree format. The position accuracy (best case) is 2.5m CEP (Circular Error of Probability).
The PhidgetSpatial Precision 0/0/3 is a 3-axis accelerometer that can measure up to ±8g of acceleration in each axis, and has high precision when measuring acceleration within ±2g. The transition from high precision to low precision mode and back is completely seamless and automatic.
This sensor buffers a piezoelectric transducer. As the transducer is displaced from the mechanical neutral axis, bending creates strain within the piezoelectric element and generates voltages.
