Introduction
Zigbee Door/Window Sensor
User Manual
SNZB-04PR1 is a Zigbee 3.0 protocol-based door/window sensor equipped with a tamper-proof feature. It senses the open and close status of doors and windows by detecting the proximity of the transmitter and magnet. This sensor seamlessly interacts with other smart devices to easily create various scenarios, such as automatically turning on lights when a door is opened, triggering audible and visual alarms in case of unauthorized entry, and sending app notifications to keep you informed.
