Overview
The Inventory Master’s LoRaWAN tracker with motion sensing power monitoring data log is an Open Source LoRaWAN Tracker based on ESP32 MCU and Semtech LoRa Wireless Chip. In this device, there are various sensors such as GPS, Wi-Fi, BLE, Temperature, Humidity, Motion Detection, and Buzzer. User can use it for different tracking scenario. This device is program friendly. Developers can use Arduino IDE to customize the software of it to fit their IoT solution. The LoRa wireless technology used in this device 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. It is equipped with a 1000mAh Li-on rechargeable battery. Each device has a worldwide unique OTAA keys to join the LoRaWAN network
