The Dragino D20/D20S-LS is a LoRaWAN Temperature Sensor for Internet of Things solution. D20/D20S-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/D20S-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/D20S-LS can measure -55°C ~ 125°C with accuracy ±0.5°C (max ±2.0 °C).
D20/D20S-LS supports temperature alarm feature, user can set temperature alarm for instant notice. D20/D20S-LS supports Datalog feature, it can save the data when there is no LoRaWAN network and uplink when network recover.
D20/D20S-LS supports BLE configure and wireless OTA update which make user easy to use.
D20/D20S-LS is powered by solar powered + Li-ion battery it is designed for long term use up to 5 years.
D20/D20S-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.
