CPL03-NB is designed for outdoor use. It has a weatherproof enclosure and industrial level battery to work in low to high temperatures.
CPL03-NB supports different uplink methods including MQTT, MQTTs, UDP & TCP for different application requirement, and support uplinks to various IoT Servers.
CPL03-NB supports BLE configure and OTA update which make user easy to use.
CPL03-NB is powered by 8500mAh Li-SOCI2 battery, it is designed for long-term use up to several years.
CPL03-NB has optional built-in SIM card and default IoT server connection version. Which makes it works with simple configuration.
