["The TrackerD is an open source LoRaWAN tracker based on an ESP32 and the Semtech LoRa wireless chip. The TrackerD contains various sensors and connection options: GPS, WiFi, BLE, temperature, humidity, motion detection and a buzzer. Due to this diversity, it can be used in many different application scenarios. The TrackerD can be programmed using the Arduino IDE. This offers the opportunity to adapt the software to your own IoT solution. The LoRa technology used in TrackerD allows the user to send data over long distances with low bandwidth. It offers ultra-long range spread spectrum communication with extremely long range and high interference immunity with minimal power consumption and is aimed at professional location services. The TrackerD has a rechargeable 1000mAh Li-on battery.
