D22-CB - NB-IoT/LTE-M Dual Outdoor Temperature Sensor

The Dragino D22-CB is a NB-IoT and LTE-M Dual Temperature Sensor for Internet of Things solution. It can be used to measure the temperature of air or object, and then upload to IoT server via NB-IoT/LTE-M network.

The temperature sensor used in D22-CB is DS18B20, which can measure -55°C ~ 125°C with accuracy ±0.5°C (at -10°C to +85°C). The outside of the sensor cable is made of silicone, and the connection between metal probe and cable is double compress for waterproof, moisture-proof and anti-rust for long term usage. The length of the cable is 1.5 m and the rating is IP68.

D22-CB supports temperature alarm feature, user can set temperature alarm for instant notice.

You can use various IoT Servers and different uplink methods including MQTT, MQTTs, UDP and TCP. 

The sensor node uses Quectel BG95-NGFF Multi-band LTE Cat M1/Cat NB2 module with GPS which can be used in most European countries. It has a card slot for an NB-IoT/LTE-M SIM card.

This device supports BLE for easy configuration and wireless OTA to update the firmware.

D22-CB is powered by 8500mAh Li-SOCI2 battery and has an IP66 enclosure. It is designed for many years of use.
