The Dragino D23-LS is a LoRaWAN Temperature Sensor for the Internet of Things solution. D23-LS is designed for use in soil or on roads. D23-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 D23-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 D23-LS can measure -55°C ~125°C with accuracy ±0.5°C (max ±2.0 °C).
D23-LS supports a temperature alarm feature, user can set a temperature alarm for instant notice. D23-LS supports the Datalog feature, it can save the data when there is no LoRaWAN network and uplink when the network recovers.
D23-LS supports BLE configure and wireless OTA update which make users easy to use.
D23-LS is powered by a solar+ Li-ion battery, designed for long-term use of up to 5 years.
Each D23-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.
