Also known as: IoT, Internet of Things
The Internet of Things (IoT) is the network of everyday physical objects — sensors, appliances, wearables — with embedded computing and connectivity that lets them send and receive data.1
Overview
IoT devices are typically built on cheap wireless microcontrollers like the ESP32, each reporting its readings to a server or the cloud. Individually each node is tiny; collectively they number in the billions.
Where it fits
The appeal of IoT is putting just enough computing into ordinary objects to make them measurable and controllable from afar. Those same low-power wireless nodes are part of the radio landscape: their transmissions are among the signals filling the airwaves GopherTrunk listens to, though the devices themselves are far too small to run it.
