Originally coined by Massachusetts Institute of Technology researcher Kevin Ashton in the late 1990s, the term “Internet of things” refers to the networking of small physical devices such as sensors, cameras and microphones through the internet. Enabled by recent advances in artificial intelligence and low-power microprocessors, technology giants such as Amazon and Google have brought affordable smart speakers — Alexa and Home respectively — to consumers. In addition, many companies are now producing smart lightbulbs and thermostats which can be operated through a smartphone app or devices such as smart speakers. The possibilities offered by these devices cannot be understated. IoT devices offer an economical means of collecting data, streaming music and making homes more energy efficient.
