Référence interne: D22-LB-EU868

The Dragino D22-LB is a&nbspLoRaWAN Temperature Sensor&nbspfor Internet of Things solution. D22-LB has 2 temperature probes. D22-LB will convert the Temperature reading to LoRaWAN wireless data and send to IoT platform via LoRaWAN gateway.

The LoRa wireless technology used in D22-LB 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 D22-LB can&nbspmeasure -55&degC ~ 125&degC with accuracy &plusmn0.5&degC (max &plusmn2.0 &degC).

D22-LB&nbspsupports temperature alarm feature, user can set temperature alarm for instant notice. D22-LB supports Datalog feature, it can save the data when there is no LoRaWAN network and uplink when network recover.

D22-LB&nbspsupports BLE configure&nbspand&nbspwireless OTA update&nbspwhich make user easy to use.

D22-LB is powered by&nbsp8500mAh Li-SOCI2 battery, it is designed for long term use up to 5 years.

Each D22-LB 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.
