Sensor Platforms

Here is a compilation of sensor platforms I have been developing or working with.

Nokia Motionband

2005
A simple wireless sensor for motion tracking
Used in various collaboration projects with Nokia
Sensors: 3x Accelerometer, 3x Magnetometer, 3x Gyro
Bluetooth connectivity
Low power MSP430 CPU
Applications: 6DOF 9DOF orientation tracking, motion sensing, gaming. A virtual reality snow boarding game was developed where postures of the player were tracked by two motionbands. Another application was head tracking for 3D audio rendering.
I used this platform extensively when developing sensor algorithms

2007
An open source R&D platform for sports, wellness, interaction and other research
Used in various collaboration projects with Nokia
It was available for purchase
Sensors: 3x Accelerometer, 3x Magnetometer, 3x Gyro, Barometer, Humidity, Temperature, Microphone, Light
Colour display, RGB LED, touch pad, buzzer, vibra
Bluetooth connectivity
Support for external Bluetooth GPS receiver
Support for inductive heart-rate strap
Powerful and flexible FPGA based, Nios II soft-core processor
Applications: heart rate monitor, step counter, sports tracking, compass, altimeter, navigation, audio analyzer, augmented reality, games, 6DOF 9DOF 10DOF 11DOF orientation tracking, dead reconing
I developed half of the electronics (sensor and user-interface board), most of the VHDL design for the FPGA and almost all of the embedded software, including architecture, sensor algorithms, wireless interface protocols and demo applications

2009
A small sensor subsystem used in reserach of motion tracking
Used in various collaboration projects with Nokia
An open library for interfacing to the sensor was publicly available
Powerful ARM7 processor allowed real-time on-device signal processing
Sensors: 3x Accelerometer, 3x Magnetometer, 3x Gyro, Barometer, Temperature
In a snowboarding event in Helsinki the movements of the snowboarders were tracked using Ariane.
My sensor algorithms (compass calibration and 6DOF orientation) were used in this platform. I used Ariane as motion sensor for our interactive performance called RAJA, which combined indoor positioning and motion sensing of dancers to synthesize visuals and sound.

2013
Open-source hardware and software platforms for flight control and stabilization of fixed wing and multirotor aircraft
Sensors: 3x Accelerometer, 3x Gyro, 3x Magnetometer, Barometer, external GPS receiver
I used this platform on my quadcopter drone I have built myself to experiment with high performance and low latency sensor fusion for flight stabilization

2016
ARM Cortex M4 core with 32 kB RAM and 256 kB Flash
Bluetooth Smart support using multi-protocol Sub-GHz to 2.4 GHz wireless radio SoC
Low Energy Consumption
Sensors: 6-axis Inertial Sensor ICM-20648, Relative Humidity and Temperature Sensor Si7021, UV and Ambient Light Sensor Si1133, Pressure Sensor BMP280, Indoor Air Quality and Gas Sensor CCS811, MEMS Microphone SPV1840
I used this platform to investigate new IoT possibilities and developed a sleep quality sensing system

2017
A OEM module for quick and easy development of products requiring motion and heart-rate sensing
Modules and development kits available for purchase
Bluetooth Smart
Sensors: Can be directly snapped to a heart rate belt. Also, includes motion sensors.
This was an odd project for me. I was asked to help with the development, but nothing with sensor processing, which I'm an outstanding expert on. I made a proprietary bootloder, not my cup of tea, which they eventually did not use. There already existed a standard compliant bootloader provided by the chip vendor.
