The Aqara Zigbee Door and Window Sensor 3 Pack is a wireless contact sensor designed mainly for home security and automation.

The sensor is battery-powered with included lithium metal batteries, providing convenience without wiring but requiring occasional battery replacement. With a maximum range of about 400 inches from the hub, it suits most average-sized homes, though placement of the hub and sensors close enough to each other and the Wi-Fi router is important for reliable performance.

Its compact size allows for versatile placement options, which is particularly beneficial for various door and window configurations around your home. With a reliable Z-Wave connectivity range of up to 250 feet to the base station, it offers solid coverage for most living spaces.
