The Central 3323-C micro door window sensor works with compatible Zigbee HA 1.2 smart home hubs and systems to monitor doors, windows, cabinets, drawers etc for open and close position.

Use it with your smart home system to automatically turn on lights when a door opens, send a notification when a door or window opens, or get alerted when a monitored cupboard or drawer opens.  Great for keeping an eye on gun storage, medical/pill storage or alcohol storage cabinets.

The 3323-C works on a single CR-2450 battery (included).
