IoT (Internet of Things) technologies refer to the network of physical devices, vehicles, home appliances, and other items embedded with electronics, software, sensors, actuators, and connectivity which enable these objects to connect and exchange data. Here are some key aspects and technologies associated with IoT:
- Sensors and Actuators: IoT devices are equipped with sensors to collect data from their environment (temperature, pressure, humidity, etc.) and actuators to act upon the data (like adjusting a thermostat based on temperature readings).
- Connectivity: IoT devices often utilize various connectivity options such as Wi-Fi, Bluetooth, Zigbee, LTE, or even satellite to communicate with each other and with centralized systems.
- Cloud Computing: Data collected by IoT devices is often processed and stored in cloud-based platforms that provide scalability, storage, and computing power necessary for IoT applications.
- Edge Computing: In some cases, IoT devices utilize edge computing where data is processed closer to the device itself, reducing latency and reliance on centralized cloud services.
- Security: IoT devices pose significant security challenges due to their distributed nature and the vast amount of data they collect. Security measures include encryption, authentication, and secure software updates.
