The Internet of Things (IoT) refers to a network of interconnected devices or objects that communicate and exchange data with each other over the internet. These devices, often embedded with sensors, actuators, and communication modules, can collect, transmit, and receive data, enabling them to interact with the physical world and each other.

Here's how IoT works:

Sensors and Devices:

IoT devices are equipped with sensors to monitor various environmental parameters such as temperature, humidity, motion, light, and more. These sensors capture data from the physical world and convert it into digital signals.

Connectivity:

IoT devices are connected to the internet or local networks using communication technologies such as Wi-Fi, Bluetooth, Zigbee, LoRa, or cellular networks. This connectivity allows devices to transmit and receive data, enabling remote monitoring and control.

Data Transmission:

Once the data is captured by sensors, IoT devices transmit it to centralized servers, cloud platforms, or other connected devices for processing and analysis. Data transmission can be periodic, event-driven, or triggered by specific conditions.
