D22 NB-IoT LTE CAT-M Waterproof Outdoor Temperature Sensor (2 probes)
D22 NB-IoT LTE CAT-M Waterproof Outdoor Temperature Sensor (2 probes)
The Dragino D22-NB or D22-CB is a NB-IoT LTE CAT-M Temperature Sensor for Internet of Things solution. D22-NB or D22-CB will convert the Temperature reading to upload the sensor data sent to IoT platform via NB-IoT LTE CAT-M network.
The temperature sensor used in D22 can measure -55°C ~ 125°C with accuracy ±0.5°C (max ±2.0 °C).
D22 supports a temperature alarm feature, user can set a temperature alarm for instant notice. D22 supports the Datalog feature, it can save the data when there is no NB-IoT network and uplink when the network recovers.
D22 supports different uplink methods including MQTT, MQTTs, UDP & TCP for different application requirements, and supports uplinks to various IoT Servers.
D22 supports BLE configure and OTA updates which make users easy to use.
D22 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.
