Smart Sensor is designed for precision. It measures distance in
) intervals as well as cadence and G-forces with a built-in 3-axis accelerometer. The main sensor body attaches to the chain-stay. The small magnetic field sensor, connected by wire, is positioned next to the rear hub. It transmits precise motion data via Bluetooth to the VeloComputer
TM mobile application.
VeloComputerTM Smart Sensor is available in 3 versions:
RIDER, SPORT and PRO
All versions feature 1° precision and:
PRO adds POWER
Like a compass!
Unlike traditional cycling sensors, which count a full 360° of wheel revolution the VeloComputerTM Smart Sensor measures the angle Omega by detecting the position of magnet M using it's magnetic field. As little as 1° of rotation is enough to detect wheel motion. (Watch the video -->>)
This precision allows the VeloComputerTM smart phone application to calculate distance, spot speed and acceleration.
Built-in 3 axis accelerometer helps to calculate grade of incline. All these data is used to calculate propulsion (output) power.
Power = Force * Velocity and Force = Mass * Acceleration
