This project is a classic educational or hobbyist-level IoT implementation. With 4 stars and nearly 3 years of inactivity, it lacks the momentum or technical complexity to be considered a defensible asset. It uses commodity hardware components (Arduino Uno, SIM800L) and standard library implementations for generic sensors. The SIM800L module relies on 2G networks, which are being sunsetted in many regions, making the hardware choice increasingly obsolete. Competitively, this project is easily replicated by following any number of online tutorials (e.g., Instructables or Hackster.io). In the professional market, companies like Xylem (YSI) or specialized startups provide high-precision, calibrated, and ruggedized versions of this hardware, while the open-source community has largely moved toward more powerful ESP32 or LoRaWAN-based solutions for better power management and connectivity.
