DRAGINO DRA D22-LB - LoRa Sensor Node, Temperature, Outdoor

" D22-LB - LoRaWAN Waterproof /Outdoor Temperature Sensor LoRaWAN 1.0.3 Class A Ultra-low power consumption 2 x DS18B20 Temperature sensors Measure range -55°C ~ 125 °C Temperature alarm Bands: EU868 Support Bluetooth v5.1 and LoRaWAN remote configure Support wireless OTA update firmware Uplink on periodically Downlink to change configure IP66 Waterproof Enclosur 8500 mAh Battery for long term use The Dragino D22-LB is a LoRaWAN Temperature Sensor for Internet of Things solution. 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. 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.
