Wireless Door Sensor Monitoring

Wirelessly monitor the open status of a storage unit’s door with the XW-111™ (for storage facilities with an available Wi-Fi network).

Configure the XW-111 to monitor the state of a magnetic contact sensor attached to a storage unit’s door. Send email/text notifications to you or your customer’s cell phone when a storage unit door is open.

The XW-111 requires no wiring and can be run on two AA batteries for low-power applications such as this.


  • Works on Wi-Fi
  • Battery or AC line powered
  • Remote sensor monitoring
  • Email/text alerts
  • Remote relay control (for audio or visual alarm)

Wireless Door Sensor Monitoring

In this example, the XW-111 is mounted on the inside of the storage unit. It is then wired to a magnetic contact sensor that is attached to the storage unit’s door.

Text/Email Temperature Alerts

The XW-111 wakes up whenever the door sensor’s break contact, which then triggers the XW-111 to send an email/text notification.

Audio/Visual Alarms

In addition to the email/text alert, you can also configure the XW-111 to trigger an audio or visual alarm (i.e., an alarm light) located in a remote location.
