DS03A-CB LTE-M & NB-IoT Outdoor Open/Close Door/Gate Sensor
The Dragino DS03A-CB is an Open/Close LTE-M & NB-IoT Door Sensor. It detects door open/close status and uplinks to IoT server via LTE-M & NB-IoT network. DS03A-CB can connect two door sensors. user can see the door status, open duration, open counts in the IoT Server.
The DS03A-CB will send periodically data every 4 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-CB can count each open event and uplink periodically.
DS03A-CB has a Datalog feature, it will record the open/close event and the user can retrieve the history from LTE-M & NB-IoT.
DS03A-CB 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-CB is designed for outdoor use. It has a weatherproof enclosure and industrial level battery to work in low to high temperatures.
NarrowBand-Internet of Things (NB-IoT) is a standards-based low power wide area (LPWA) technology developed to enable a wide range of new IoT devices and services. LTE-M & NB-IoT significantly improves the power consumption of user devices, system capacity, and spectrum efficiency, especially in deep coverage.
DS03A-CB supports different uplink methods including TCP, MQTT, UDP, and CoAP for different application requirements.
DS03A-CB is powered by 8500mAh Li-SOCI2 battery, It is designed for long-term use of up to 5 years. (Actually Battery life depends on the use environment, update period & uplink method)
