Description
System Overview
You take a modular hardware platform and you couple it with an optimized system firmware. Then you select the latest MEMS sensors and equip a dual-core ARM Cortex microcontroller. Add Bluetooth communication, a USB-C interface and a 1Gb FLASH memory. Finally, you program it with sensor fusion and other embedded AI software. That’s how you get Muse: a low power, miniaturized, wireless multi-sensor logger.
Our customers have used Muse as wireless IMU, motion tracker, sport sensor, vibration sensor, magnetic sensor, impact sensor, temperature sensor, humidity sensor, Bluetooth beacon, black box logger, smart alarm, and every day we keep enjoying its versatility.
The secret is in its name. Muse stands for multi-sensor which means the system is ideal for a variety of wearable and IoT applications that require a reliable, state-of-the-art and certified product platform.
What’s Included
In its FULL configuration, the system features: 1x tri-axis accelerometer , 1x tri-axis gyroscope, 1x tri-axis magnetometer , 1x High Dynamic Range tri-axis accelerometer , 1x temperature sensor , 1x relative humidity sensor , 1x high resolution barometer , 1x microphone and 1x ambient light & distance time of flight sensor .
The INERTIAL configuration includes: 1x tri-axis accelerometer, 1x tri-axis gyroscope, 1x tri-axis magnetometer.
The system is highly miniaturized in a 22x22x5.85 mm PCB form factor. It includes a 110 mAh rechargeable lithium-ion battery (alternatively it can be powered directly by the 5V USB-C plug or the expansion port). Data logging memory is provided by a 1Gb NAND Flash memory. MUSE includes a push button for ON/OFF operations or programmable functions (e.g. start/stop logging), visual interaction RGB LEDs and an acoustic interaction buzzer.
The optional housing is a 3d printed PA enclosure ensuring mechanical protection of the system. 3D CAD files are available if you wish to customize your own enclosure.
