D23-NB NB-IoT Waterproof /Outdoor Temperature Sensor node

The Dragino D23-NB is an NB-IoT Temperature Sensor that supports three Temperature Sensor probes which are based on DS18B20 for Internet of Things solutions. D23-NB will convert the Temperature reading to upload the sensor data sent to the IoT platform via the NB-IoT network.

The temperature sensor used in D23-NB can measure -55°C ~ 125°C with accuracy ±0.5°C (max ±2.0 °C).

D23-NB supports a temperature alarm feature, user can set a temperature alarm for instant notice. D23-NB supports the Datalog feature, it can save the data when there is no NB-IoT network and uplink when the network recovers.

D23-NB supports different uplink methods including MQTT, MQTTs, UDP & TCP for different application requirements, and supports uplinks to various IoT Servers.

D23-NB supports BLE configure and OTA updates which make users easy to use.

D23-NB is powered by an 8500mAh Li-SOCI2 battery, it is designed for long-term use up to several years.

D23-NB has an optional built-in SIM card and default IoT server connection version, which makes it work with a simple configuration.
