A wheel loosening sensor 100 for fitting in a recess 204 on an internal surface of a wheel 200 and for detecting movement of the wheel away from a wheel hub 202, the wheel loosening sensor comprising: a transmitter configured to transmit a signal when movement of the wheel away from the wheel hub is detected; and an antenna 130 in electrical communication with the transmitter and configured such that at least part of the antenna is deeper within the recess than the transmitter when the wheel loosening sensor is fitted within the wheel. The wheel loosening sensor may comprise a protrusion (312, Fig.3) in which at least part of the antenna is located. The protrusion may have a smaller cross sectional area than the main body (302). The sensor may comprise a removable cap (401, Fig.4) covering the protrusion which may have one or more ridges configured to create an interference fit with the recess to retain the sensor in position. Also claimed is a wheel comprising a recess on an internal surface; a wheel loosening sensor assembly or kit of parts comprising a sensor and a spacer (530,Fig.5); and a vehicle comprising a wheel having a recess.
