The Dragino D22-NB is an NB-IoT Temperature Sensor that supports two Temperature Sensor probes, which are based on DS18B20 for Internet of Things solutions. D22-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 D22-NB can measure -55°C ~ 125°C with accuracy ±0.5°C (max ±2.0 °C).
D22-NB supports a temperature alarm feature, the user can set a temperature alarm for instant notice. D22-NB supports the Datalog feature, which can save the data when there is no NB-IoT network and uplink when the network recovers.
D22-NB supports different uplink methods, including MQTT, MQTTs, UDP & TCP for different application requirements, and supports uplinks to various IoT Servers.
D22-NB supports BLE configuration and OTA updates which making it easy to use.
D22-NB is powered by an 8500mAh Li-SOCI2 battery, it is designed for long-term use up to several years.
D22-NB has an optional built-in SIM card and default IoT server connection version, which makes it work with a simple configuration.
