DRAGINO Sensor LoRa Temperature Sensor Node Outdoor D23-LB-EU868

The Dragino D23-LB is a LoRaWAN temperature sensor for Internet of Things solutions. D23-LB has 3 temperature sensors. The D23-LB converts the temperature readings into wireless LoRaWAN data and sends it to the IoT platform via the LoRaWAN gateway.
The LoRa wireless technology used in the D23-LB allows the device to send data and achieve extremely long ranges at low data rates. It offers spread spectrum communication with extremely long range and high interference immunity with minimal power consumption.
The temperature sensor used in D23-LB can measure -55°C ~ 125°C with an accuracy of ±0.5°C (maximum ±2.0°C).
D23-LB supports temperature alarm function, user can set temperature alarm for instant notification. D23-LB supports datalog function and can save the data when there is no LoRaWAN network and uplink when the network is restored.
D23-LB supports BLE configuration and OTA wireless update, which makes it easier for users to use.
The D22-LB is powered by an 8500mAh Li-SOCI2 battery designed for long-term use of up to 5 years.
Each D22-LB is pre-loaded with a set of unique keys for LoRaWAN registrations. These keys are registered on the local LoRaWAN server and the connection is established automatically after switching on.
