SoundOfMotion releases new VeloComputer 9-axis Smart Sensor platform at the Bluetooth SIG media event. The Smart Sensor can be mounted on a bicycle wheel hub, crank or a seat post to measure speed, acceleration, cadence, crank position and slope grade; it can also be used in other sports measuring various motion with help of SDK.

"Developers can use SDK to measure various motion with the sensor. Running, swinging, swimming or jumping - you are limited only by your imagination," said founder Vlad Savchenko.

SoundOfMotion releases new VeloComputer 9-axis Smart Sensor platform at the Bluetooth SIG media event in New York City. The new sensor supports Bluetooth Smart wireless technology as well as ANT+. Bluetooth is used in smartphones, like Android, iPhone and new generation of smart watches. ANT+ is used primarily by Garmin sport watches and cycling monitors. The new sensor uses no magnets to measure speed, acceleration, cadence and road gradient.

When mounted on a wheel hub the VeloComputer 9-axis Smart Sensor can detect forward and reverse wheel motion with 1-inch precision. It is 100 times more accurate than any traditional cycling speed sensor. This precision reduces data latency and allows accurate calculation of spot speed and acceleration. The sensor attaches to a wheel hub with a simple snap-over mount without any tools. It is powered by a standard coin cell battery.

“Cyclists have to adjust a magnet on a spoke after transporting the bike or changing a wheel,” said founder Vlad Savchenko. “This is a hassle. Traditional speed sensors use a magnet to count wheel revolutions. This gives only 7 feet precision in distance measurement.”

VeloComputer 9-axis Smart Sensor can also be mounted on a seat post of a bicycle to measure grade of a slope, cadence, lean angle and fall detect. Using magnetometer, gyro and accelerometer the sensor instantly detects change of a road slope, measured in percentage (%). The cadence is extracted from a lateral motion of the seat post, when the cyclist is pedaling, and measured in rotations per minute – (RPM). The sensor attaches to a seat post of a bicycle with a simple snap-over mount without any tools.

When the sensor is mounted on a crank it measures frequency of the pedal strokes as well as the crank position and angular acceleration. This data is used to detect the backpedaling effect when cyclists resist their own pedaling effort by inadvertently pushing on a pedal in a recovery position.

The sensor supports standard Bluetooth Smart and ANT+ speed and cadence profiles with 360-degree or 7 feet precision. It also offers 1-inch precision in distance, spot speed, acceleration and grade of incline, using custom Bluetooth Smart profiles with VeloComputer application for Android and iPhone.

SoundOfMotion offers a software developer kit (SDK) for developers to create new use cases for VeloComputer 9-axis Smart Sensor platform. Developers can use SDK to measure various motion with the sensor. "Running, swinging, swimming or jumping - you are limited only by your imagination," said Vlad Savchenko.

The new VeloComputer 9-axis Smart Sensor can be pre-ordered at VeloComputer.com for $39. The retail price of the sensor is $59. The cost of SDK is $99.
