By measuring the acceleration of the robot, one can calculate the velocity of the robot, and more importantly the distance this robot has traveled. Accelerometers are also great for detecting collisions and determining if the robot is stopped or moving.
The LIS344ALH capacitive micromachined accelerometer features signal conditioning, a 1-pole low pass filter, temperature compensation and g Select which allows for the selection among 2 sensitivities. Zero-g offset full scale span and filter cut-off are factory set and require no external devices.
Three Axis Accelerometer.
Selectable sensitivity via jumper: ±2g and ±6g.
0-5V analog output (one for each axis).
Uses the LIS344ALH chip.
LED indicated power and proper connection.
Mounts directly to VEX.
