DESCRIPTION

This Wireling features the high performance and low power Bosch BMA250 3-axis accelerometer. The BMA250 allows measurement of accelerations in three perpendicular axes and thus senses tilt, motion, shock, and vibration in your projects. There is also an integrated temperature sensor built-in.
