Abstract

A component monitoring apparatus [100] including an input [110] to receive sensor data from a sensor arrangement [S1-S4]. The sensor data representative of a use of a respective component [105] during a monitoring interval. A memory [118] provided to store received sensor data and a life parameter associated with the component [105], an interface [126] provided to communicate with a remote device and a power cell [128] provided to power the apparatus [100]. The apparatus [100] arranged to: store in the memory [118] received sensor data, in response to a trigger, read the sensor data from the data memory [118] and transfer the sensor data to the remote device, and, in response to receipt of a data packet containing a life parameter associated with the usage of the component [100], store the life parameter to the memory [122].
