PNI's SENtral-K hub for Google's KitKat handles all the hardware connections to the MEMS sensors plus manages the virtual sensor functions in software and in dedicated state-machine logic.
This is some good news. Battery life in Andriod is a critical issue. If this can improve the battery life of the phone and tab, very nice and needed. But how one implement it on existing devices that are already in the market and being used.
No it does not house sensors, one need to buy the sensors separately, the interface IC is only providing connecting interface for controlling and sensing the sensors output all together. Yes it has interface for all the sensors used in Smartphone.
SENtral-K is offering exceptional performance like 10 fold power saving at the same cost. Only the disadvantage is that the sensor needs to provide I2C output. Interfacing original sensors directly will not be supported. I am not sure how many manufacturers are directly interfacing bare sensors via on chip A/D converters. If they are using bare sensors then that is the catch here, otherwise SENtral-K will be proved the best sensor hub for androids.
I am really amazed to see the size of the sensor hub - 1.6 mm x 1.6 mm! It is awfully tiny, given all that it has...kind of a small microcontroller. Does it work with specific sensors from specific manufacturers? Or it works with any of the sensors from different manufacturers having I2C interface?
