Speaking with, Product Manager PAT at Sartorius Soenke Rosemann said biomanufacturers “need to monitor oxygen and carbon dioxide concentrations in bioreactors to ensure cells are healthy, to see what metabolic state they are in and how active they are,” without having to take samples and analyse them in a laboratory. High accuracy real-time clock: 5ppm over the entire temperature range from -40☌ to +85☌ It has high speed motion sensing (raw data and orientation as quaternions) up to 500Hz.for measurements once a day)īlueSense addresses the needs of sensor research (it's an extensible platform) for wearable applications (it has a form factor smaller than what you would get with an Arduino or Teensy), with high-speed motion sensing (up to 500Hz currently, up to 1KHz in upcoming revision) which is useful for sports application or use in robotic setups.

This makes the platform also suitable for sensor research, IoT applications, or as an compact alternative to other microcontroller boards. Other featuresīesides USB, Bluetooth 2 and SD card interface with a FAT32 compatible filesystem, BlueSense has a real-time clock, a coulomb counter to measure it’s own battery level and power consumption, true hardware off, and connectors for extensions. It has been optimised for high-speed motion data logging and streaming (500Hz), and high-speed external ADC acquisition (1+KHz), informed by the need of wearable motion tracking and activity recognition applications. The application firmware has been designed to be useful for a wide range of applications out of the box. The extension ports allow to plug in custom sensor modalities which make this device highly versatile. This allows to achieve very long battery life, as the device can wake up at desired times (once an hour, once a day, …) to acquire and send sensor data. IoT platformĪs an IoT device it’s main appeal is a true hardware off which allows to put the device entirely to sleep (everything is powered down, including voltage regulators), yet wake up at programmed intervals thanks to a real-time clock wakeup. A display is being developed converting it into a smartwatch. Its extension ports allow to plug-in additional sensor modalities for research purposes.

BlueSense could be used to prototype a custom fitness tracker. The data can either be logged on an SD card or streamed over USB or Bluetooth 2. Wearable motion sensingĪs a wearable platform, BlueSense is a tiny device which can be used to capture body movement and orientation with a 9DoF motion sensor. Yet it is extensible for IoT applications with a number of features making it appealing for this purpose. It’s primary purpose is to be an inertial measurement unit for wearable applications based on the Invensense MPU9250 and an AT1284p microcontroller. It is designed to be functional out-of-the-box yet extensible. BlueSense is a 30x30mm extensible platform for wearable motion sensing, sensor research and IoT applications.
