D22-LS Solar powered LoRaWAN Waterproof /Outdoor with 2 x DS18B20 Temperature Sensor

The Dragino D22-LS is a LoRaWAN Temperature Sensor for the Internet of Things solution. D20-LS is designed for use in soil or on roads. D22-LS will convert the Temperature reading to LoRaWAN wireless data and send it to the IoT platform via the LoRaWAN gateway.

The LoRa wireless technology used in D22-LS allows the 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-LS can measure -55°C ~125°C with accuracy ±0.5°C (max ±2.0 °C).

D22-LS supports a temperature alarm feature, the user can set a temperature alarm for instant notice. D22-LS supports the Datalog feature, which can save the data when there is no LoRaWAN network and uplink when the network recovers.

D22-LS supports BLE configuration and wireless OTA update, which makes it easy to use.

D22-LS is powered by a solar+Li-ion battery, designed for long-term use of up to 5 years.

Each D22-LS is pre-loaded with a set of unique keys for LoRaWAN registrations, register these keys to the local LoRaWAN server, and it will auto-connect after powering on.
