An example of an Internet of Things (IoT) device is a smart thermostat. This device allows users to monitor and control their home temperature remotely through a smartphone app or web interface. Smart thermostats utilize sensors and data analytics to learn user preferences and adjust settings accordingly, optimizing energy usage. By connecting to Wi-Fi, these devices enable users to manage heating and cooling systems efficiently, resulting in cost savings and improved comfort. As part of a broader IoT ecosystem, smart thermostats can also integrate with other devices for enhanced home automation functionality.
