The Dragino CPN01 is an NB-IoT Dry Contact Sensor. It detects open/close status and uplinks the info to IoT server via NB-IoT network. User can see the dry contact status, open time, and open counts in the IoT Server.

The CPN01 will send periodically data every day as well as for each dry contact action. It also counts the contact open times and calculates the last open duration. Users can also disable the uplink for each Open/Close event, instead, device can count each open event and uplink periodically.

CPN01 has Open-Alarm feature, user can set this feature so CPN01 will send an alarm if the contact has been open exceeds a certain time.

CPN01 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.

CPN01 supports different uplink methods including TCP, MQTT, UDP, and CoAP for different application requirements.

CPN01 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 CPN01, user needs to check if there is NB-IoT coverage in the field and with the Nb-IoT bands that CPN01 supports. If local operator support it, user needs to get a NB-IoT SIM card from the operator and install into CPN01 to get NB-IoT network connection.
