ISense hardware

The modular iSense hardware collection

iSense is a modular hardware and software platform for wireless networks that is intended for both industry and research applications (see the figure below). The hardware is arranged around a core module that provides computation and communication to each sensor node. It is equipped with an IEEE 802.15.4 [9] compliant radio, a 32-bit RISC controller running at 16MHz, 96kbytes of memory, a highly accurate clock and a switchable power regulator.

It can be combined with a number of sensor modules (including a thermometer, a light sensor, an accelerometer, a passive infrared sensor, a magnetometer for vehicle detection and a camera), different power sources (in-system rechargeable lithium-ion secondary battery, ultra compact 1/2 AA primary battery and traditional AA battery holders), a gateway and I/O module as well as various others. The hardware is supplemented with a modular operating and networking firmware that is based on object oriented programming. Like this, application specific sensor nodes can be constructed just by plugging together hardware modules containing the required functionality.
