D20S-CB - NB-IoT/LTE-M Waterproof Temperature Sensor

The Dragino D20S-CB is a NB-IoT and LTE-M Temperature Sensor for Internet of Things solution. It can be used to measure the temperature of liquid or soil, and then upload to IoT server via NB-IoT/LTE-M network.

The temperature sensor used in D20S-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 TPE for waterproof, moisture-proof and anti-rust for long term usage. The length of the cable is 2m.

D20S-CB supports temperature alarm feature. You 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.

D20S-CB is powered by 8500mAh Li-SOCI2 battery and has an IP66 enclosure. It is designed for many years of use.
