Dragino TrackerD -- LoRaWAN Tracker

TrackerD is an Open Source LoRaWAN Tracker based on ESP32 MCU and Semtech LoRa Wireless Chip. In TrackerD, there are various sensors such as GPS, WiFi, BLE, Temperature, Humidity, Motion Detection, and Buzzer. User can use TrackerD for different tracking scenario. TrackerD is program friendly. Developers can use Arduino IDE to customize the software of TrackerD to fit their IoT solution.

The LoRa wireless technology used in TrackerD 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.

TrackerD is equipped with a 1000mAh Li-on rechargeable battery. Each TrackerD has a worldwide unique OTAA keys to join the LoRaWAN network.
