D20 NB-IoT LTE CAT-M Waterproof Outdoor Temperature Sensor
The Dragino D20-NB and D20-CB is an NB-IoT LTE CAT-M Temperature Sensor for Internet of Things solutions. D20-NB/D20-CB will convert the Temperature reading to upload the sensor data send to the IoT platform via the NB-IoT LTE CAT-M network.
The temperature sensor used in D20-NB/D20-CB can measure -55°C ~ 125°C with accuracy ±0.5°C (max ±2.0 °C).
D20-NB/D20-CB supports a temperature alarm feature, user can set a temperature alarm for instant notice. D20-NB supports the Datalog feature, it can save the data when there is no NB-IoT network and uplink when the network recovers.
D20-NB/D20-CB supports different uplink methods including MQTT, MQTTs, UDP & TCP for different application requirement, and supports uplinks to various IoT Servers.
D20-NB/D20S-NB supports BLE configure and OTA update which make user easy to use.
D20-NB/D20S-NB is powered by an 8500mAh Li-SOCI2 battery, it is designed for long-term use up to several years.
