DRAGINO - LoRaWan 3-probe battery-powered waterproof temperature sensor

Dragino D23-LB Temperature Sensor

The Dragino D23-LB is a LoRaWAN temperature sensor designed for IoT applications requiring precise measurement over long distances. Equipped with 3 DS18B20 temperature probes, it can monitor temperatures from -55°C to +125°C with a typical accuracy of ±0.5°C. Thanks to LoRa technology, this sensor transmits data efficiently and with very low power consumption.
