A smart device is an electronic device, generally connected to other devices or networks via different wireless protocols such as Bluetooth, Zigbee, NFC, Wi-Fi, LiFi, 5G, etc., that can operate to some extent interactively and autonomously. Several notable types of smart devices are smartphones, smart cars, smart thermostats, smart doorbells, smart locks, smart refrigerators, phablets and tablets, smartwatches, smart bands, smart key chains, smart speakers and others. The term can also refer to a device that exhibits some properties of ubiquitous computing, including—although not necessarily—artificial intelligence.

A smart battery or a smart battery pack is a rechargeable battery pack with a built-in battery management system (BMS), usually designed for use in a portable computer such as a laptop. In addition to the usual positive and negative terminals, a smart battery has two or more terminals to connect to the BMS; typically the negative terminal is also used as BMS "ground". BMS interface examples are: SMBus, PMBus, EIA-232, EIA-485, and Local Interconnect Network.

Bzigo is a technology start-up company that developed an autonomous device that detects and locates mosquitoes. The company was founded by Nadav Benedek and Saar Wilf.
A smart key is an electronic access and authorization system that is available either as standard equipment, or as an option in several car designs. It was first developed by Siemens in 1995 and introduced by Mercedes-Benz under the name "Keyless-Go" in 1998 on the W220 S-Class, after the design patent was filed by Daimler-Benz on May 17, 1997.

Home Assistant is a free and open-source home automation software designed to be the central home automation control system for controlling smart home technology. Home Assistant "core" application software itself is written in Python and its main focus is on local-control and privacy.

Pixel Buds are a line of wireless earbuds developed and marketed by Google. The first generation of the Pixel Buds were launched on October 4, 2017 at Google's Made By Google launch event and were available for preorder on the Google Store the same day. They have the Google Assistant built-in and support Google Translate.

Playmation is a system of toys, wearables, and companion apps from Disney and Hasbro. The system is designed to keep kids active, replacing screens with pretend play. Players can receive missions through a companion app, and track scores and accomplishments.

A guided bomb is a precision-guided munition designed to achieve a smaller circular error probable (CEP).

A smart camera or intelligent camera is a machine vision system which, in addition to image capture circuitry, is capable of extracting application-specific information from the captured images, along with generating event descriptions or making decisions that are used in an intelligent and automated system. A smart camera is a self-contained, standalone vision system with built-in image sensor in the housing of an industrial video camera. It contains all necessary communication interfaces, e.g. Ethernet, as well as industry-proof 24V I/O lines for connection to a PLC, actuators, relays or pneumatic valves. It is not necessarily larger than an industrial or surveillance camera. A capability in machine vision generally means a degree of development such that these capabilities are ready for use on individual applications. This architecture has the advantage of a more compact volume compared to PC-based vision systems and often achieves lower cost, at the expense of a somewhat simpler user interface. Less powerful versions are often referred to as smart sensors.

In computing, Smart Display was a Microsoft initiative to use a portable touchscreen LCD monitor as a thin client for PCs, connecting via Wi-Fi.

Home automation or domotics is building automation for a home, called a smart home or smart house. A home automation system will monitor and/or control home attributes such as lighting, climate, entertainment systems, and appliances. It may also include home security such as access control and alarm systems. When connected with the Internet, home devices are an important constituent of the Internet of Things ("IoT").

A smart lock is an electromechanical lock which is designed to perform locking and unlocking operations on a door when it receives such instructions from an authorized device using a wireless protocol and a cryptographic key to execute the authorization process. It also monitors access and sends alerts for the different events it monitors and some other critical events related to the status of the device. Smart locks can be considered part of a smart home.

Smart modules are a type of solar panel that has a power optimizer embedded into the solar module at the time of manufacturing. Typically the power optimizer is embedded in the junction box of the solar module. Power optimizers attached to the frame of a solar module, or connected to the photovoltaic circuit through a connector, are not properly considered smart modules.

The Smart Personal Objects Technology (SPOT) is a discontinued initiative by Microsoft to create intelligent and personal home appliances, consumer electronics, and other objects through new hardware capabilities and software features.

Smart thermostats are thermostats that can be used with home automation and are responsible for controlling a home's heating, ventilation, and air conditioning. They perform similar functions as a Programmable thermostat as they allow the user to control the temperature of their home throughout the day using a schedule, but also contain additional features, such as sensors and WiFi connectivity, that improve upon the issues with programmable thermostats.

Smart traffic lights or Intelligent traffic lights are a vehicle traffic control system that combines traditional traffic lights with an array of sensors and artificial intelligence to intelligently route vehicle and pedestrian traffic. They can form part of a bigger intelligent transport system.

A smart transducer is an analog or digital transducer or actuator combined with a processing unit and a communication interface.

An interactive whiteboard (IWB), also known as interactive board or smart board, is a large interactive display in the form factor of a whiteboard. It can either be a standalone touchscreen computer used independently to perform tasks and operations, or a connectable apparatus used as a touchpad to control computers from a projector. They are used in a variety of settings, including classrooms at all levels of education, in corporate board rooms and work groups, in training rooms for professional sports coaching, in broadcasting studios, and others.

The Unihertz Atom phone is billed as the smallest rugged smartphone. Following the Unihertz Jelly in 2017, in 2018, Unihertz produced another successful smart phone, the more capable Unihertz Atom, initially through a similar kickstarter project that reached its $50,000 goal in only 60 seconds.
