Detect the opening/closing of doors with the Adeunis Contact Sensor. Ideal for a variety of applications this sensor combines a dry contact transceiver with a proximity switch and magnet set.

Simply attach the proximity switch to your chosen door to:

  • Ensure doors are closed in cold storage areas and refrigerators
  • Monitor when secure premises are accessed
  • Prevent intrusion
  • Maintain records of the number of times an area is accessed

Utilising LoRaWAN® technology, the Adenuis Contact Sensor can be configured to raise alarms when activity is detected. Data recorded by the sensor is transmitted periodically via a LoRaWAN® gateway and network server enabling you to view the collected information on your chosen dashboard. This information could then be used to optimise efficiencies in cleaning regularly used areas or to address potential issues in cold areas before they arise.

For peace of mind, this contact sensor features an in-built cable cut detection which will automatically alert you to any potential tampering.

  • Robust IP67 rated casing (IP68 available on request)
  • Transmission on event (alert) or periodic (counting)
