The present invention concerns sensor apparatus (1) for an article comprising a unique apparatus identifier and an in-use sensor, the in-use sensor determining whether the apparatus is in an in-use or a dormant condition. The in-use sensor comprises a light sensor for measuring light falling on the apparatus and one or more accelerometers for measuring orientation and vibration of the apparatus, wherein an in-use condition is determined from reviewing whether measurements from the light sensor and one or more accelerometers exceed threshold values.
