Shimmer Wireless Sensor Unit/Platform
Description
Shimmer is a low power wireless sensor platform that provides much of the functionality needed for wireless sensing. Designed for wearable sensing applications, the platform has an on-board microcontroller, wireless communication via Bluetooth or 802.15.4 low power radio, and the option of local storage to a micro SD card. The unit also has an integrated accelerometer for motion sensing, activity monitoring and inertia measurement applications. The Shimmer unit acts as a baseboard for the full range of Shimmer wireless sensor modules. Shimmer can be connected to any one of a range of sensors such as Gyro, Magnetometer, ECG, EMG, GSR, GPS/Temperature, or Strain Gauge modules, whilst maintaining its small, lightweight, and wearable form factor.Features and Benefits
