Portable electronic device
An Intelligent Sensor Interfacing Unit (ISIU) for detection and configuration of sensors for a Portable Electronic Device (PED). The ISIU may identify sensors connected to the PED, according to an implementation of the present subject matter. The ISIU then determines information relating to the capabilities and requirements of the identified sensors. The ISIU on the basis of the determined sensor information may access that one of the sensors' identified may be newly coupled to the PED. Further, the ISIU upon accessing that one of the sensors' may be newly coupled to the PED, shares sensor information with Host CPU of the PED. The Host CPU upon receiving such information configures the newly coupled sensor and trains the ISIU for execution of the newly coupled sensor in future.
