How IoT Works
IoT devices usually contain sensors that collect data. The collected data is then sent to a
cloud server through the internet. This data is analyzed, and based on the analysis,
specific actions are taken. For example, a smart thermostat can measure the
temperature of a house and adjust it accordingly.
