DS03A-NB -- NB-IoT Open/Close Door Sensor

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

The DS03A-NB 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-NB can count each open event and uplink periodically.

DS03A-NB supports Datalog Feature,it can save the data when there is no NB-IoT network and uplink when network recover.

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

DS03A-NB supports different uplink methods including MQTT, MQTTs, UDP & TCP for different application requirement, and support uplinks to various IoT Servers.

DS03A-NB supports BLE configure and OTA update which make user easy to use.

DS03A-NB is powered by 8500mAh Li-SOCI2 battery, it is designed for long-term use up to several years.

DS03A-NB has optional built-in SIM card and default IoT server connection version. Which makes it works with simple configuration.
