Overview
The Inventory Master’s LoRaWAN GPS tracker with Wi-Fi & BLE for smart homes is an open source LoRaWAN Tracker based on ESP32 MCU and Semtech LoRa Wireless Chip. In this, there are various sensors such as GPS, WiFi, BLE, Temperature, Humidity, Motion Detection, and Buzzer. Users can use it for different tracking scenarios. It is program friendly. Developers can use Arduino IDE to customize the software to fit their IoT solution. The LoRa wireless technology used in it 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.
