Elsys EMS Door Mini LoRaWAN Indoor Sensor

Elsys EMS Door LoRaWAN sensors can easily detect the open/closed status of doors and windows which makes them perfect for your smart building, smart home and smart office projects.

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 unlocked door or window in a restricted area. This can be particularly useful when monitoring IT server (clean) rooms, freezers or temperature controlled areas and loading bays.
