1. Introduction
Netvox ZA02A, a ZigBee air pollution sensor, acts as a Router Device in ZigBee network. ZA02A is featured to
play a role of the sensor (Zone device) in the ZigBee security system. It can detect NH3, NO2, Ethanol (EtOH),
SO2, and smoke. When the air quality goes below a specified level, ZA02A would generate the sound to alert users.
ZA02A will also 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.
