The Dragino D20-NB and D20S-NB is an NB-IoT Temperature Sensor for Internet of Things solutions. D20-NB/D20S-NB 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/D20S-NB can measure -55°C ~ 125°C with accuracy ±0.5°C (max ±2.0 °C).
D20-NB/D20S-NB supports the temperature alarm feature. Users can set temperature alarms for instant notice. D20-NB supports the Datalog feature. It can save data when there is no NB-IoT network and uplink when the network recovers.
D20-NB/D20S-NB supports different uplink methods including MQTT, MQTTs, UDP & TCP for different application requirements, and supports uplinks to various IoT Servers.
D20-NB/D20S-NB supports BLE configure and OTA update, making users 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.
D20-NB/D20S-NB has an optional built-in SIM card and default IoT server connection version, which makes it work with a simple configuration.
