He is the Editor-in-Chief of Journal of Imaging. vii Preface to ”State-of-the-Art Sensors Technology in Spain 2017” Since 2009 six special issues has been published on sensors and technologies in Spain, where researchers present their successful progress. Forty high quality works have been collected and reproduced on this book, demonstrating significant achievements. They are self-contained works addressing different sensor-based technologies, procedures and applications on several areas with a wide range of devices and useful developments. Readers will also find an excellent source of resources when necessary in the development of his research, teaching or industrial activity. Although the book is focused on sensors and technologies in Spain, it describes worldwide ad- vanced developments and references on the covered topics useful on the contexts addressed. Some works have been or come from international collaborations. Our society is demanding new technologies for data acquisition, processing and transmission

INTEL EDISON- A SOC based on Intel Atom The Intel Edison compute module is designed to lower the barriers to entry for anyone prototyping and producing IoT and wearable computing products. Intel Edison contains the core system processing and connectivity elements: processor, PMIC, RAM, eMMC, and Wi- Fi/BT. Intel Edison is a module that interfaces with end-user systems via a 70-pin connector. The Intel Edison compute module does not include any video input or output interfaces (MIPI CSI, MIPI DSI, HDMI, etc.). Internal image processing and graphics processing cores are disabled (ISP, PowerVR, VED, VEC, VSP, etc.). Intel Edison relies on the end-user support of input power.

Run example code Intel® Edison Arduino Expansion Board Assembly https://software.intel.com/en‐us/articles/intel‐edison‐arduino‐expansion‐board‐assembly Microswitch and USB Ports Details The slider switches between USB host mode and USB device mode. Device mode: The switch is toggled down and a micro‐USB cable can be used to turn the Intel® Edison into a computer peripheral. Device mode allows you to do such things as: program the board over USB, or mount the onboard flash memory like a disk drive. Host mode: The switch is toggled up and USB peripherals with a standard‐sized USB cable (such as mice, keyboards, etc) can be plugged into the Intel® Edison. USB host mode requires the use of an external power adapter. The Intel Edison board has three USB ports: The middle port (Micro A type) is used for the following: •Power through USB •Ethernet over USB •Uploading Arduino sketches •Updating the firmware by using the board as a storage device, like a flash drive The edge port (Micro A type) is used to create a terminal connection by serial over USB only. Power Through DC Plug If you are going to use more power intensive features such as Wi‐Fi, a servo motor, or an Arduino shield, use a DC power supply in addition to the device mode micro‐USB cable.

Arduino family of boards network storage having high popularity and large number of sold units featuring Some or all of these functionalities can be present including open access, reliability, robustness, standard connections and low prices, possesses large potential for implementation of also some specific not mentioned here. Mentioned autonomous remote measurement and control systems of various functionalities are quite general and do not pose limitations by levels of complexity. As Arduino boards can function themselves, as the real limits of IoT devices are mainly independently, they are complete small computer platforms that determined by processing power, speed, available memory, can perform various tasks requiring some kind of interaction with power consumption and similar characteristics. If the task for the outer world. Arduino boards can be used and programmed in some IoT device is too demanding, the possibility of logically various ways, and can be arranged in various combinations redefining the task so that more than one IoT device could be forming some typical implementation architectures that this paper used and combined to fulfill the given task, should be discusses.
