Zigbee is a low-power wireless communication protocol designed for connecting devices in an Internet of Things (IoT) network. It is based on the IEEE 802.15.4 standard and is designed for low-cost, low-power wireless networks that require low data rates. It is used in a variety of IoT applications, including home automation, health monitoring, smart energy, and industrial automation.
For example, Zigbee can be used to connect a variety of sensors in a home automation system, such as motion detectors, temperature sensors, and light switches. This allows the system to monitor and control the environment in the home, such as turning on lights when motion is detected or adjusting the temperature based on the current temperature.
