Use of triaxial accelerometers to identify sheep behaviour. Schematic of (a) sensor axis orientations and, photographs of (b) standing (left) and lying (right) postures and the corresponding X axis orientation of a leg deployed accelerometer, (c) orientation of a collar mounted accelerometer during grazing activity (note the forward tilt of the sensor) and (d) changes in the X axis orientation of an ear deployed accelerometer during walking behaviour.
