DS03A-NB will send periodic 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.
In the event of network outages, the DS03A-NB can save data when there is no NB-IoT network and uplink when the network recovers.
A configurable alarm can be set so that 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 (-40 ~ 85°C)
