NODE+ Wireless Sensor Platform

www.variableinc.com


Wireless Sensor Platform

NODE+ Features For fitness, logistics, vibration analysis, and gaming, motion is only as good as it is useful. NODE+motion measures nine degrees of motion with a 9DOF IMU, which allows NODE+ to accurately measure its orientation and movement.

Technical Specifications

This is made possible through the combination of a three-axis gyroscope, a three-axis accelerometer, and a three-axis magnetometer.

NODE+ transmits accurate data via Bluetooth 4.0 to your iOS smart device up to 250 feet away.

NODE+motion makes sensing movement truly mobile.

Other interchangeable sensor modules can be attached to either end of the NODE, thus expanding functionality.
