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

The Dragino D20-NB/NS and D20S-NB/NS is an NB-IoT Temperature Sensor for Internet of Things solutions. D20-NB/NS and D20S-NB/NS 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 D20-NB/NS and D20S-NB/NS can measure -55°C ~ 125°C with accuracy ±0.5°C (max ±2.0 °C).

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

D20-N/NSB supports BLE configure and OTA update which make users easy to use.

D20-NB/NS is powered by an 8500mAh Li-SOCI2 battery or Solar Panel + Li-on Battery, it is designed for long-term use up to several years.

D20-NB/NS has an optional built-in SIM card and default IoT server connection version. Which makes it work with a simple configuration.
