D22-NB NB-IoT Waterproof Temperature Sensor (2 probes)
The Dragino D22-NB is a NB-IoT Temperature Sensor for Internet of Things solution. D22-NB will convert the Temperature reading to upload the sensor data sent to IoT platform via 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, user can set a temperature alarm for instant notice. D22-NB supports the Datalog feature, it 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 configure and OTA updates which make users 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 optional built-in SIM card and default IoT server connection version. Which makes it works with simple configuration.
