D22-NB -- NB-IoT Waterproof /Outdoor Temperature Sensor

Description

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 send 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 temperature alarm feature, user can set temperature alarm for instant notice. D22-NB supports Datalog feature , it can save the data when there is no NB-IoT network and uplink when network recover. D22 -NB supports diferent uplink methods including MQTT, MQTTs, UDP & TCP for diferent application requirement, and support uplinks to various IoT Servers. D22 -NB supports BLE confgure and OTA update which make user easy to use. D22 -NB is powered by 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 confguration. Common DC Characteristics : NB-IoT Module: BC660K-GL
