The Mulle - A wireless sensor node
The Mulle is a miniature wireless Embedded Internet System (EIS) suitable for wireless sensor networking and rapid prototyping.
The Mulle platform has an ultra-low power consumption and its large number of I/Os makes it ideal as a building block for wireless sensors. The Bluetooth version is capable of communicating with most Bluetooth-enabled devices, e.g. computers, PDAs and mobile phones. The use of TCP/IP enables the Mulle to transmit sensor data directly to the Internet and the small form factor allows it to be easily embedded in any product.
The Mulle software is open-source using a modified BSD license. The software can be compiled with IAR's Embedded Workbench or the free
GNU gcc compiler.
All Mulle versions have the same external connector and core configuration, as well as on-board battery monitor with integrated temperature sensor. Radio and on-board sensor for the various versions are:
- ver 3.1: Bluetooth 2.0 (class 2, 10 m), low-power high speed temperature sensor.
- ver 3.2: Bluetooth 2.0 (class 2, 10 m), 3-axis accelerometer.
- ver 4.1: Bluetooth 2.0 (class 1, 100 m), low-power high speed temperature sensor.
- ver 5.2: IEEE 802.15.4 2.4 GHz (ZigBee, 200 m), 3-axis accelerometer.
- ver 6.2: IEEE 802.15.4 868 MHz (ZigBee, 1000 m), 3-axis accelerometer.
