Dragino CPL03 Dry Contact Sensor (LoRaWAN, NB-IoT & LTE-M)
The Dragino CPL03 Dry Contact Sensor is designed for reliable monitoring of open and closed states from external dry contact devices using LoRaWAN, NB-IoT, and LTE-M networks. It provides a straightforward way to connect switches, relays, buttons, and third-party equipment to an IoT platform for remote status visibility and alerting.
Simple Contact State Monitoring The CPL03 is suited to applications where simple state detection is required rather than analogue measurement. Common use cases include monitoring equipment run states, safety switches, pump status, alarms, and other contact-based signals across industrial, commercial, and infrastructure environments.
Multi-Network Connectivity The CPL03 is available in variants supporting LoRaWAN, NB-IoT, and LTE-M, allowing deployment on private LoRaWAN networks or carrier-operated cellular networks. This flexibility supports fixed installations, remote sites, and locations where cellular coverage is preferred.
Enhanced Monitoring with Telemetry2U When combined with the Telemetry2U IoT platform, the CPL03 Dry Contact Sensor can be configured with dashboards, alerts, and historical data logging. Telemetry2U helps transform simple state changes into practical monitoring outcomes, providing visibility, notifications, and long-term tracking from a single platform.
