Acronym for Signal Phase & Timing.
The service set identifier (SSID) is chosen by the client device that starts the network. 
An open I/O standard, owned and maintained by FPGA designer Opal Kelly, for high-performance peripheral connectivity. 
Acronym for Software as a Service.
Security Information and Event Management
Software and services offering real-time monitoring, event correlation, file integrity monitoring, notifications and console views. 
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. 
A rotary actuator used for angular positioning, with sensor feedback for precise control. 
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. 
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). 
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. 
Spaced Repetition
A quantified self concept designed to increase the brain's retention of knowledge. 
Steel Collar
Things in the workplace that replace or augment human labor. 
Subscriber Identity Module
Provided by the Mobile Network Operator, a SIM contains the International Mobile Subscriber Identity (IMSI) and the security parameters to authenticate access to the network.
Supervisory Control and Data Acquisition
SCADA is an industrial control system typically used for geographically dispersed assets, often scattered over large distances. 
Swarm Robotics
A combination of swarm intelligence and robotics, these multi-robot systems consist of a large number of small robots, communicating locally, that are capable of collective behaviors similar to that of insects. 
System on a Chip
A single integrated circuit (IC) technology that contains all the necessary circuits and parts for a complete "system." A single microchip in a wearable device, for example, could contain an analog-to-digital converter, memory, logic control, I/O, etc.
