** The Dragino D20-LS is a LoRaWAN Temperature Sensor for Internet of Things solution. D20-LS will convert the Temperature reading to LoRaWAN wireless data and send to IoT platform via LoRaWAN gateway.

** The LoRa wireless technology used in D20-LS allows device to send data and reach extremely long ranges at low data-rates. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.

** The temperature sensor used in D20-LS can measure -55°C ~ 125°C with accuracy ±0.5°C (max ±2.0 °C).

** D20-LS supports temperature alarm feature, user can set temperature alarm for instant notice.D20-LS supports Datalog feature, it can save the data when there is no LoRaWAN network and uplink when network recover.

** D20-LS supports BLE configure and wireless OTA update which make user easy to use.

** D20-LS is powered by 8500mAh Li-SOCI2 battery or solar powered + Li-ion battery it is designed for long term use up to 5 years.

** Each D20-LS is pre-load with a set of unique keys for LoRaWAN registrations, register these keys to local LoRaWAN server and it will auto connect after power on.
