Aprašymas

"Dragino Technology D20S-LB. Purpose: Outdoor, Sensor type: Temperature sensor, Type: Freestanding. Width: 120 mm, Depth: 55 mm, Height: 200 mm"\n"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."
