The Dragino DS03A-LB/LS is a LoRaWAN Door Sensor for Internet of Things solution. It detects door open/close status and uplinks to IoT server via LoRaWAN network. user can see the door status, open duration, open counts in the IoT Server.

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

The DS03A-LB/LS will send periodically data every 2 hours as well as for each door open/close action. It also counts the door open times and calculates the last door open duration. Users can also disable the uplink for each open/close event, instead, DS03A-LB/LS can count each open event and uplink periodically.

DS03A-LB/LS supports Datalog Feature, it can save the data when there is no LoRaWAN network and uplink when network recover.

DS03A-LB/LS has the Open Alarm Feature, user can set this feature so the device will send an alarm if the door has been open for a certain time.

DS03A-LB/LS is designed for outdoor use. It has a weatherproof enclosure and industrial level battery to work in low to high temperatures

DS03A-LB/LS supports BLE configure and wireless OTA update which make user easy to use.

DS03A-LB/LS is powered by 8500mAh Li-SOCI2 battery or solar powered + li-on battery, it is designed for long term use up to 5 years.

Each DS03A-LB/LS is pre-load with a set of unique keys for LoRaWAN registrations, register these keys to local LoRaWAN server and it will auto connect after power on.
