NDS03A NB-IoT Outdoor Open/Close Door/Gate Sensor
The Dragino NDS03A is an Open/Close NB-IoT Door Sensor. It detects door open/close status and uplinks to IoT server via NB-IoT network. NDS03A can connect two door sensors. user can see the door status, open duration, open counts in the IoT Server.
The NDS03A 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, NDS03A can count each open event and uplink periodically.
NDS03A has a Datalog feature, it will record the open/close event and the user can retrieve the history from NB-IoT.
NDS03A 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.
NDS03A 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. NB-IoT significantly improves the power consumption of user devices, system capacity, and spectrum efficiency, especially in deep coverage.
NDS03A supports different uplink methods including TCP, MQTT, UDP, and CoAP for different application requirements.
NDS03A 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)
To use NDS03A, user needs to check if there is NB-IoT coverage in the field and with the Nb-IoT bands that NDS03A supports. If local operator support it, user needs to get a NB-IoT SIM card from the operator and install into NDS03A to get NB-IoT network connection.
