Functional examples (putting it all together)
A collection of sensors alone doesn't have much value until the data they collect is transmitted, processed, or acted upon. That processing can be performed by an embedded controller or sent upstream to a cloud. More hardware is needed to build the system. Typically, the sensors will use established IO interface and communication systems, such as I2C, SPI, UART, SPI, or other low-speed IOs (covered in Chapter 11, Cloud and Fog Topologies). Other devices, such as video systems, will need much faster IOs to maintain high resolution and fast video frame rates. Such IOs would include MIPI, USB, or even PCI-Express. To communicate wirelessly, the sensors will need to be used with wireless transport hardware like Bluetooth, Zigbee, or 802.11. All this requires extra componentry, which we will cover in this section.
