Introduction
Many of the problems of excessive wiring within a car can be resolved by using a serial multiplex bus like CAN or LIN. The LIN (Local Interconnect Network, reference 1) bus is lower in cost and ideally suited to use within a door or in other areas in the car where its limited data rate of 20,000 baud is adequate. The display of external temperature is an application which falls into this category. As a common location for the outside temperature sensor is in a wing mirror, the data often originates from the door.
