D20-LB - LoRaWAN Outdoor waterproof Temperature Sensor -55 to 125C

The Dragino D20/D20S-LB or D20/D20S-LS is a LoRaWAN Temperature Sensor for Internet of Things solution. D20/D20S-LB or 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-LB or 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-LB or D20/D20S-LS can measure -55°C ~ 125°C with accuracy ±0.5°C (max ±2.0 °C).

D20/D20S-LB or D20/D20S-LS supports temperature alarm feature, user can set temperature alarm for instant notice. D20/D20S-LB or D20/D20S-LS supports Datalog feature, it can save the data when there is no LoRaWAN network and uplink when network recover.

D20/D20S-LB or D20/D20S-LS supports BLE configure and wireless OTA update which make user easy to use.

D20/D20S-LB or D20/D20S-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/D20S-LB or 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.

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.
