A sensor hub is a point of connection for multiple sensors that uses a coprocessor, digital signal processor (DSP) and a multipoint control unit (MCU) to process & compile data gathered from those sensors. Sensor hub share some of the workload which is otherwise performed by a computer. This allows the data obtained by sensors to be collected and processed with demand for computer resources and results in better performance, less power draw and free CPU time. Sensor hubs are used where multiple sensors are required to perform a specific task and demand for resources & the need for the efficiency are high. Increasing amount of data, such as environmental (pressure, humidity, temperature, light) and motion (magnetometers, gyroscopes, accelerometers) from multiple sensors needs to be fused in the system for better system performance. Sensor hub runs these complex sensor fusion algorithms, while providing maximum flexibility for a system operation.

The sensors hub market is anticipated to grow due to increasing need for the low power generating solutions for variety of mobile & wearable devices. There is an increasing need for the low power utilizing mobile devices, which can function for a longer duration without draining the battery at a faster rate. A number of mobile manufacturing companies are embedding a sensor hub in their mobile devices. The sensor hub continuously collects the sensor data keeping the main processor idle and saves the battery life of a mobile device. For instance, Google introduced the Android sensor hub which can hooked directly into a phone’s sensors. Data from the gyroscope, fingerprint reader, accelerometer and many other sensors can funnel into the small scale processor running Google’s custom algorithms.
This allows the Sensor Hub to interpret gestures and activities independently and can extend battery life significantly by consume minimal amount of power. Furthermore, QuickLogic Corporation introduces S1 Wearable sensor hub which is a context aware and ultra-low power sensor hub that is optimized for next-generation advance wearable applications. It can be used for the functions such as pedometer including separate step counts for walking & running and consumes less amount of power.
The factor restraining the growth of the sensors hub market is the technical complexity in a deployment of a sensor hub. There is a need of advance level expertise for the effective & efficient deployment of the sensor hub in a smartphone or a wearable device due to the complex technology.
