    2023

    I successfully integrated the ED10W LoRaWAN GPS Watch from Origoelec and WisBlock GNSS Tracker from RakWireless with a custom LoRa antenna using the RAK5146 kit, which had a range of 2 kilometers. By connecting the antenna to The Things Network, I received hex-formatted watch data in PHP, which I processed and seamlessly integrated into IoT dashboard widgets.

    The IoT Platform Dashboard is a cloud-based management system designed to control and monitor Internet of Things (IoT) devices. Using machine-to-machine (M2M) communication, users can easily add their IoT devices and view real-time data. This project offers various features such as IoT data analysis and smart device control, making it ideal for home and industrial system monitoring.
