Collected data points from (a) in-field CH\(_4\) measurements [ppm], (b) tri-axial accelerometer signals per node, and (c) tri-axial gyroscope signal per node. The four labels represent the position and motion of the cow’s head during the measurements: Up-still refers to the cow standing up without head movement. Up in-motion indicates the cow standing while either walking or moving the head. Down-still corresponds to the cow lying on the ground without head movement. Down in-motion refers to the cow lying on the ground while either eating or moving the head.
