1. A sensing device for sensing an environmental parameter, comprising:
a measurement module configured for providing a sequence of measurement values in dependence on the environmental parameter,
a communication module configured for communicating with a further sensing device,
a function analysis module coupled to the measurement module and the communication module, the function analysis module comprising:
a first stage comprising a recurrent neural network for determining a first temporal feature on the basis of the sequence of measurement values, wherein the recurrent neural network is configured to perform all neural processing to determine the first temporal feature, and the first temporal feature is determined based on measurement values of only the sensing device, and
a second stage comprising a graph neural network for determining information about a functional state of the measurement module on the basis of input comprising the first temporal feature, a second temporal feature provided by the further sensing device, and spatial information comprising a relative spatial arrangement between the sensing device and the further sensing device, wherein the measurement module, the communication module and the function analysis module are co-located together, and the further sensing device is external to the sensing device.
