Zigbee
Zigbee is a low-power, wireless mesh networking protocol designed for short-range communication in Internet of Things (IoT) and smart home applications. It operates on the IEEE 802.15.4 standard and enables devices like sensors, lights, and switches to connect and communicate efficiently with minimal energy consumption. The protocol supports mesh networking, allowing devices to relay data through other nodes to extend range and improve reliability.
Developers should learn Zigbee when building IoT systems, especially for smart homes, industrial automation, or energy management, where low power usage, scalability, and reliable communication are critical. It is ideal for battery-operated sensors (e.g., temperature, motion, door/window) that need to operate for years without frequent battery changes, and its mesh topology enhances coverage in large or obstructed environments. Use cases include home automation hubs, environmental monitoring, and asset tracking in constrained networks.
