Description

The Dragino LSN50v2-D23 is a LoRaWAN Temperature Sensor for the Internet of Things solution. It can be used to 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 can measure -55°C ~ 125°C with accuracy ±0.5°C (max ±2.0 °C). There are three sensor cables that are waterproof, moisture-proof, and anti-rust for long-term usage.

LSN50v2-D23 supports temperature alarm feature, user can set temperature alarm for instant notice.

LSN50v2-D23 is powered by 8500mAh Li-SOCI2 battery, It is designed for long-term use up to 10 years. (Actually Battery life depends on the use environment, update period. Please check the related Power Analyze report).

Each LSN50v2-D23 is pre-load with a set of unique keys for LoRaWAN registration, register these keys to local LoRaWAN server and it will auto-connect after power on.
