Zigbee is a wireless communication protocol designed for low-power, low-data rate applications. It operates on the IEEE 802.15.4 standard and is commonly used in home automation, industrial controls, and other short-range communication scenarios. Zigbee networks are known for their low energy consumption and ability to connect multiple devices in a mesh network. This makes it ideal for IoT applications where devices need to communicate efficiently and reliably without frequent recharging.
