Temperature sensors - Dragino - D22-LB

LoRaWAN Temperature Sensor for the Internet of Things

The Dragino D22-LB/LS is a LoRaWAN temperature sensor designed for IoT solutions, converting temperature readings into wireless data sent via a LoRaWAN gateway.

Long Range LoRa Technology

Using LoRa technology, the D22-LB/LS sends data over very long distances at low data rates, with wide-area communication and high interference resistance, while minimizing power consumption.

Temperature Range and Accuracy

The D22-LB/LS temperature sensor can measure from -55°C to 125°C with an accuracy of ±0.5°C (maximum ±2.0°C).

Temperature Alarm and Datalog Functionality

The D22-LB/LS supports a temperature alarm function for instant notifications and can record data in the absence of a network, transmitting it when the connection is reestablished.

BLE Configuration and OTA Update

BLE configuration and wireless OTA updates make the device easy to use.

Power Supply and Lifespan

Powered by an 8500mAh Li-SOCI2 battery or a solar + Li-ion battery combination, the D22-LB/LS is designed for long-term use of up to 5 years.

LoRaWAN Pre-registration Keys

Each D22-LB/LS is preloaded with a set of unique keys for LoRaWAN registrations, enabling automatic connection after power-up.
