Wireless sensor devices for animal tracking and control

The paper describes some new wireless sensor hardware developed for pastoral and environmental applications. From our early experiments with Mote hardware, we were inspired to develop our devices with improved radio range, solar power capability, mechanical and electrical robustness, and with unique combinations of sensors. Here we describe the design and evolution of a small family of devices: radio/processor board; a soil moisture sensor interface; a single board multisensor unit for animal tracking experiments.
