Description
The Dragino CPL03-LB is a LoRaWAN open-close dry contact sensor. It detects an open or close and sends the data to an IoT server via a LoRaWAN network. The CPL03-LB sends the information via LoRaWAN network. The LWL02 sends data every day and (optionally) when there is a dry contact action. The dry contact status, contact open time, and last contact open duration are viewable in the IoT server.
The CPL03-LB supports BLE configuration and wireless OTA update for ease of use. The device is powered by an 8500 mAh Li-SOCl₂ battery, designed for long-term use of up to 5 years.
The CPL03-LB has a datalog feature that records data even when there is no network coverage, allowing users to retrieve the logged sensor values. Additionally, the CPL03-LB features an open alarm system. For example, an alarm is sent if the contact has been open for a set time length.
Each CPL03-LB comes preloaded with a set of unique keys for LoRaWAN registration that when registered, would automatically connect the device to the LoRaWAN server after powering on
