It is ideal for areas where access needs to be monitored. This wireless sensor sends an alert message to a centralised monitoring system via the LoRaWAN® protocol when a window or door is opened.


  • Compatible with the LoRaWAN® protocol
  • Requires 2 x CR2450 3v batteries (sold separately)
  • Built-in antenna
  • Simple operation and device configuration
  • Reports battery voltage and window/door contact status
  • Up to 5 years’ battery life (dependent on conditions)
  • Wireless range of up to 10km
  • Data is encrypted and secure
LoRaWAN® door contact sensors are the future of smart security. These devices can be used for commercial and residential properties to monitor access. They can be used to alert property owners to an open door or window in a restricted area. This can be particularly useful when monitoring IT server (clean) rooms, freezers or temperature controlled areas and cargo bays. We can supply third-party online wireless sensor monitoring and notification system to view data and set alerts via SMS text and email. Ask us about our zero-touch provisioning service, this sensor can be supplied pre-configured and ready to go.
