Dragino D20-NB NB-IoT Waterproof /Outdoor Temperature Sensor

The Dragino D20-NB is a NB-IoT Temperature Sensor for Internet of Things solution. D20-NB will convert the Temperature reading to upload the sensor data send to IoT platform via NB-IoT network.

The temperature sensor used in D20-NB can measure -55°C ~ 125°C with accuracy ±0.5°C (max ±2.0 °C).

D20-NB supports temperature alarm feature, user can set temperature alarm for instant notice. D20-NB supports Datalog feature, it can save the data when there is no NB-IoT network and uplink when network recover.

D20-NB supports diferent uplink methods including MQTT, MQTTs, UDP & TCP for diferent application requirement, and support uplinks to various IoT Servers.

D20-NB supports BLE confgure and OTA update which make user easy to use.

D20-NB is powered by 8500mAh Li-SOCI2 battery, it is designed for long-term use up to several years.

D20-NB has optional built-in SIM card and default IoT server connection version. Which makes it works with simple confguration.
