âCooking up a connected productâ Adding a connected device to your portfolio can be challenging. Jonathan Pallant looks at how to pick the âperfect ingredientsâ.
Connected devices tend to sit at the more complex end of the embedded system spectrum, irrespective of whether they gather sensor data by themselves or interface with pre-existing equipment.
Their complexity arises from the interaction between their three constituent parts: the local part, which generates the data or needs some control; the far system which records the data and/or provides instructions; and the connection between them, which typically operates over a large distance and is often observable (and even interruptible) by untrustworthy third parties.
