Before we dive into the specifics of the Zigbee Relay Module, it's important to understand the Zigbee protocol itself. Zigbee is a low-power, short-range wireless communication standard used for creating personal area networks (PANs). It operates in the 2.4 GHz frequency band and is designed for low data rate, low power consumption, and long battery life, making it ideal for IoT devices and applications that require minimal power usage over extended periods. Zigbee’s mesh networking capability also allows devices to communicate with each other across large distances, creating reliable and robust networks.
