What are Things/devices in IoT?

In IoT, Things are physical objects that include sensors (and often actuators) and a way to connect to the Internet. They gather data from the real world—like temperature, humidity, motion, or light—and can send that data to apps or cloud services. They can also receive commands to act on the environment, such as turning on a heater or adjusting a valve. The important point is the combination of hardware, sensing/actuation, and connectivity that lets these objects participate in an IoT system. They range from everyday items like smart thermostats or wearable sensors to industrial sensors and machinery. They may run on battery or power and use various communication methods such as Wi‑Fi, cellular, Bluetooth, Zigbee, or LoRa. Cloud services store and process the data, but the Things themselves are the physical devices with sensors and connectivity—not software-only services, nor limited to end-user devices.
