CPL03 NB-IoT LTE CAT-M Open/Close Dry Contact Pulse Counter and Reed SensorCPL03 NB IoT LTE CAT M Open Close Dry Contact Pulse Counter and Reed Sensor The Dragino CPL03 is an NB IoT and LTE CAT M Contact Sensor for the Internet of Things solution. It detects dry contact status, open time, open counts, and then upload to IoT server via NB IoT and CAT M network. The CPL03 will send periodically data every day as well as for each dry contact action. It also counts the contact open times and calculate last open duration. User
