Sensor: A device used to measure a specific characteristic of the surrounding environment, such as temperature. …
Sensor Fusion: The process of combining and processing the raw data coming out of multiple sensors to generate usable information. …
Serial Peripheral Interface: A specification developed by Motorola for use for short distance communication between between sensors and microcontrollers such as Arduino. …
Servomotor: A rotary actuator used for angular positioning, with sensor feedback for precise control. …
Shield: The name given to expansion boards that extend the capabilities of Arduino development boards. …
Shock Sensing: A MEMS concept referring to the detection of sudden impacts at a predetermined level. …
Signal Phase and Timing: Refers to communications associated with the operations of signalized intersections. …
Signal-to-Noise Ratio: The strength of an electrical or other desired signal relative to background noise. …
Single Board Computer: A complete, functioning computer with all functions (I/O, processor, memory) located on one board. …
Smart Grid: A general term referring to the application of networking capabilities and computer systems to the electric grid. …
Smart Pigs: An industrial device, known as a "pig," that is moved through pipelines to inspect for damage, defects and leaks. …
Smartwatch: A wristwatch, generally with a display, that interacts with the wearer and can communicate with a network wirelessly (the device may have a USB connection for charging and other functions). …
SoC: Acronym for System on a Chip.
Software as a Service: A subscription-based model where a monthly fee is charged for using software, rather than an upfront purchase. …
Software-Defined Networking: SDN allows administrators to manage network services by abstracting lower level functionality, allowing network services to be specified without coupling these specifications to network interfaces. …
