The Dragino LSN50v2-D23 is a LoRaWAN LoRaWAN Waterproof/Outdoor Temperature Sensor for the Internet of Things solution. It can measure the temperature of air, liquid, or object and then upload to IoT server via LoRaWAN wireless protocol.
The temperature sensor used in LSN50v2-D23 is DS18B20, which can measure -55°C ~ 125°C with accuracy ±0.5°C (max ±2.0 °C). Three sensor cables are waterproof, moisture-proof, and anti-rust for long-term usage.
LSN50v2-D23 LoRaWAN Waterproof/Outdoor Temperature Sensor
LSN50v2-D23 supports a temperature alarm feature, and users can set temperature alarms for instant notice.
LSN50v2-D23 is powered by 8500mAh Li-SOCI2 battery, It is designed for long-term use up to 10 years. (Actually, the Battery life depends on the use environment update period. Please check the related Power Analyze report).
Each LSN50v2-D23 LoRaWAN Sensor is pre-load with a set of unique keys for LoRaWAN registration, register these keys to the local LoRaWAN server and it will auto-connect after power on.

I use this sensor to monitor three freezers. They are indoors, but the sensor cost for freezer is unbeatable. So far very good. My T-bones are staying frozen. I love the Dragino outdoor case. These were easy to deploy. To get them to rejoin or power them up you have to take off the case. But that is the price of waterproof. I like this device. My tech stack is DSL08 -> TTS on Linode -> Ubidots.
