The Internet of Things (IoT) refers to digital or mechanical devices that can connect to each other and share data over a network. These “things” can be anything — from smartwatches and connected vehicles, to agriculture sensors and industrial machinery.
Because of its wide scope, IoT services can include everything from hardware provisioning to real-time analytics, device integration, data storage, and security.
Consider how the Danish Heart Foundation used IoT to detect defective defibrillators — or how an Australian farmer reduced water usage using IoT-enabled irrigation. The use cases are limitless — as long as you find the right partner to bring them to life.
If you're looking for an IoT development partner, here are eight essential criteria to consider.
