"As the Internet of Things takes off, sensors will find their way into devices that nobody has even thought of yet."
True!....The smart phones have provided the required boost to the sensors, this will increase multifold at the onset of IoT. One thing that has changed over the years, in the world of sensors, that the interface of the sensor to the host processor has become more standardized...from analog interface to standard digital interface, e.g. I2C interface.
