Dragino TrackerD-LS -- LoRaWAN Asset Tracker

TrackerD-LS is an Open Source LoRaWAN Asset Tracker based on ESP32 MCU and Semtech LoRa Wireless Chip. It can get the location data via GPS and set it to IoT server via LoRaWAN network.

TrackerD-LS supports Motion Detection, when there is motion, TrackerD-LS can send data more frequently and it will save power when no motion is detected.

The LoRa wireless technology used in TrackerD-LS allows the user 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. It targets professional tracking services.

When there is no LoRaWAN network, TrackerD-LS can save the location data. It will send these data to IoT server when there is LoRaWAN network coverage.

TrackerD-LS is equipped with a 3000mAh Li-on rechargeable battery + Solar Panel which let the device can be used for many years. Each TrackerD-LS has a worldwide unique OTAA keys to join the LoRaWAN network.

TrackerD-LS is program friendly. Developers can use Arduino IDE to customize the software of TrackerD-LS to fit their IoT solution.
