D23-LB/LS – Waterproof LoRaWAN Temperature Sensor – Dragino
 General Description
 Dragino 's D23-LB/LS is a LoRaWAN temperature sensor designed for outdoor environments. It uses one or more Dallas DS18B20 probes to measure temperatures from -55°C to +125°C with an accuracy of ±0.5°C. Thanks to its IP66 waterproof housing, it is ideal for installations in industrial or agricultural environments.
 The D23-LB is powered by an 8500mAh Li-SOCI2 battery while the D23-LS version is equipped with a solar panel and 3000mAh Li-ion battery . It integrates advanced features like Bluetooth configuration, configurable temperature alarms, OTA firmware update, and data logging in case of connection loss.
