IOTA door sensor, equipped with SIGFOX wireless transmission module, allows to detect if and when doors are opened/closed.

It is being used mostly to monitor doors/flaps in objects that are located remotely, to make sure doors/flaps are properly closed.

When doors are opened or closed, the device instantly sends a message that can be pushed as email/sms or visualised in an application.

The mechanical switch used in the device eliminates false alarms and provides high resistance against tamper.

The device has also additional features:

• informs weekly about state of battery („awake” message)
• detects movements/shocks (optionally).
