LSN50v2-D20 - Dragino LoRaWAN Temperature Sensor Node DS18B20 -55 to 125C Outdoor

The Dragino LSN50v2-D2x is a LoRaWAN Temperature Sensor for Internet of Things solution. It is used to measure the air, liquid or object temperature, and then upload to IoT server via LoRaWAN wireless protocol.

The temperature sensor used in LSN50v2-D2x can measure -55°C ~ 125°C with accurancy ±0.5°C (max ±2.0 °C). The sensor cable is waterproof, moisture-proof and anti-rust for long term usage.

LSN50v2-D2x support temperature alarm feature, user can set temperature alarm for instant notice. LSN50v2-D2x 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 related Power Analyze report).

Each LSN50v2-D2x 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.

Default FW in AS923, but it support US915, AU915 and all 900MHz Frequency by loading different FW, it could also support 868MHz if loading 868MHz FW, but there will be slight 0.5-1dB loss here.
