LoRaWAN open/closed door sensor Dragino DS03A-LB

The Dragino DS03A-LB is the solution LoRaWAN Door Sensor for the Internet of Things. It detects open/closed door status and connects to IoT server via LoRaWAN network. the user can see the status of the door, the duration of the open time, the number of open doors on the IoT server.

The LoRa wireless technology used in the DS03A-LB allows the device to send data and reach extremely long distances at low data rates. It provides ultra-long range spread-spectrum communication and high immunity to interference while minimizing current consumption.

The DS03A-LB will periodically send data every 2 hours and for every door open/close action. It also counts the time the door was opened and calculates how long the door was last opened. Users can also disable uplink for each open/close event, instead DS03A-LB/LS can periodically count each open event and uplink.

DS03A-LB supports the Datalog function, it can save data when there is no LoRaWAN network and connect when the network is restored.

DS03A-LB has open alarm function , the user can configure this function so that the device sends an alarm if the door has been opened for a certain period of time.

DS03A-LB is intended for outdoor use. It has a waterproof case and an industrial-grade battery for operation in low and high temperatures

DS03A-LB supports BLE configuration and wireless OTA update , which makes it easy for the user to use.

The DS03A-LB is powered by 8500 mAh Li-SOCI2 battery or solar + Li-ion battery , it is intended for long-term use up to 5 years. Each DS03A-LB comes pre-loaded with a set of unique LoRaWAN registration keys, register these keys to your local LoRaWAN server and it will connect automatically after power on.
