The more the merrier
Though engineers want more and more an input, they do not want more and more sensor packages. As with most aspects of electronics there is a push to integrate multiple sensors in a single package, a technique commonly called sensor fusion. We are trying to combine as many as possible into one component. If you need to understand the pressure and temperature of a fluid you’d like to combine both sensors into one device to reduce space. It is quite common to combine sensors for measuring parameters such as temperature, and pressure combination is always the best way to go. Discrete components sometimes offer more flexibility and lower costs. Although it is attractive to a conceptual standpoint, there are quite some hurdles for a large-scale adoption of sensor fusion. The associated networking costs often outweigh the cost of a standalone sensor.
