LDS02 LoRaWAN Door/Window Sensor Node 868MHz

The Dragino LDS02 is a door and window contact for LoRaWAN. A magnet in the second housing part indicates whether a door or window is open or closed, and the sensor reports the state via the LoRaWAN network. It counts the openings and reports the duration of the last opening. It runs on two AAA batteries (not included), according to Dragino they last for about 16,000 to 70,000 uplinks or 2 to 10 years.

Each LDS02 comes with its own keys for OTAA activation, so it can be registered, for example, in The Things Network. Firmware updates are done with a DAPLink adapter.
