1. Introduction
Netvox ZB11A1, an infrared radiation (IR) occupancy sensor, acts as an End Device in ZigBee network. It does not
perform permit-join function as a coordinator or a router for other devices to join the network. When ZB11A1
detects movement, it reports the message to the ZigBee network. Users can assign specific task to other devices
based on different report. ZB11A1 is also featured to play a role of the sensor (Zone device) in the ZigBee security
system. When the movement is detected, ZB11A1 will notify the central security unit, CIE (Control and Indicating
Equipment) device, to send commands to a siren device to trigger an alarm.
What is ZigBee?
ZigBee is a short range wireless transmission technology based on IEEE802.15.4 standard and supports multiple
network topologies such as point-to-point, point-to-multipoint, and mesh networks. It is defined for a
general-purpose, cost-effective, low-power-consumption, low-data-rate, and easy-to-install wireless solution for
industrial control, embedded sensing, medical data collection, smoke and intruder warning, building automation
and home automation, etc.
