Abstract
A device is configured to monitor a state of a rotatable handle of a valve when the device is attached to the rotatable handle. The device comprises a vector magnetometer configured to measure a magnetic field. The device comprises a processing unit configured to obtain from the vector magnetometer measurements of the magnetic field when the handle is rotated; calculate a change in the state of the rotatable handle based on a difference between the measurements of the magnetic field; and report the change in the state.
